How an IP Holder Should Evaluate Which Titles in Their Catalog to Adapt First
Adapted IP enters vertical drama with three structural advantages over original content. First, an existing reader or viewer base that already knows the characters and wants more story, lowering the acquisition cost of the first free episode. Second, a validated emotional structure: a novel that held readers' attention across 300 pages has proven its hook-tension-escalation mechanics work in the target market. Third, recognizable search terms: a novel title or franchise name generates organic search traffic to the platform listing in a way that original titles do not.
Those three advantages are real and commercially significant. They are also the reason that a large catalog is a selection problem rather than a selection opportunity. An IP holder with 500 titles does not have 500 vertical drama adaptation opportunities. Most of the 500 titles will not perform better in vertical drama adaptation than a well-designed original series. The titles whose specific structural characteristics align with the format's commercial mechanics are the ones whose adaptation is commercially justified.
The selection problem is specific: how do you identify the 10 to 20 titles in a 500-title catalog whose structural characteristics produce the highest probability of vertical drama commercial success? This post covers the evaluation framework that any IP holder can apply.
The Four Evaluation Criteria
Criterion 1: Power Dynamic Clarity
The single most predictive structural characteristic of a title's vertical drama adaptation potential is whether the central tension can be described as a clear power dynamic between two primary characters in one sentence.
A title whose central tension is a clear power dynamic — one character holds institutional, social, or emotional authority over the other, and the series is built around the inversion of that authority — has the structural foundation that vertical drama's paywall conversion mechanic depends on. The paywall moment is the moment before the power dynamic inverts. If the power dynamic is not clear from the title's premise, the paywall moment cannot be designed with the precision that vertical drama's monetisation model requires.
Evaluation test: can you describe the title's central tension in one sentence that contains a specific power dynamic between two named or described character configurations? If yes, the title passes. If the one-sentence description requires explanation before the power dynamic is legible, the title fails.
Passes: "A CEO whose institutional authority is the source of his identity is involuntarily drawn to the one person in his company whose read of him is accurate."
Fails: "A young woman navigates the complexities of corporate life while discovering her true potential."
The first sentence contains a specific power dynamic. The second does not.
Criterion 2: Episode Architecture Compatibility
Vertical drama's episode structure requires a story that can be divided into 70 or more units where each unit contains a discrete forward move and an unresolved tension point at its end.
Titles whose narrative structure produces episodic forward moves naturally are compatible with vertical drama's episode architecture. Titles whose narrative structure is built around sustained mood, gradual revelation, or character interiority without forward-moving plot events are not compatible.
Evaluation test: take the title's first quarter of narrative content. Can you identify 15 to 18 discrete narrative events where the protagonist's situation changes in a specific direction, a new tension is introduced or an existing tension escalates, and the event ends with a question that the next event will partially but not fully answer? If yes, the title passes.
Criterion 3: Reader or Viewer Engagement Data
The most commercially predictive data for vertical drama adaptation potential is the existing audience's engagement behavior with the source material.
For web novel or book IP: chapter completion rate above 70% across the first 25% of the narrative indicates that the story's hook-tension-escalation mechanics are sustaining reader engagement at the chapter-by-chapter level. Comment section character engagement — readers predicting character behavior, expressing emotional responses to character states, and requesting continuation — indicates parasocial investment that transfers to the vertical drama format's paywall conversion mechanics.
For television or film IP: episode completion rate above 65% for the first season indicates sustained viewer engagement. Search volume data for character names rather than title names indicates that the audience has invested in the specific characters rather than only in the narrative premise.
Evaluation test: pull the engagement data for the title's first 25% of content across the available platform analytics. Is the completion rate above 70% for sequential content units? Does the comment section or social discussion engage with character emotional states? If both, the title passes.
Criterion 4: Antagonist Specificity
The antagonist's commercial function in vertical drama is the generation of righteous anger that sustains middle-arc retention across episodes 20 through 45. A title whose antagonist commits specific, witnessed injustices against the protagonist — injustices that accumulate across the arc and are specifically addressed in the resolution — has the antagonist architecture that sustains retention.
A title whose antagonist is a diffuse force, a social system, or an internal psychological state rather than a specific character who commits specific injustices produces a middle-arc retention problem.
Evaluation test: can you name the specific antagonist and describe at least three specific injustices the antagonist commits or will commit against the protagonist across the arc? If yes, the title passes.
Applying the Four Criteria: The Scoring Framework
Apply all four criteria to each catalog title and score each criterion as pass (1) or fail (0). Maximum score: 4.
Score 4: high-priority adaptation candidate. All four structural characteristics align with vertical drama's commercial mechanics. Commission a pilot concept test before the full adaptation investment.
Score 3: viable adaptation candidate with one structural gap. Identify which criterion failed and evaluate whether the gap can be addressed in adaptation without compromising the title's identity.
Score 2: requires significant structural reworking before adaptation is commercially viable. Evaluate whether the title's IP advantages are strong enough to justify the reworking investment.
Score 0 to 1: not commercially viable for vertical drama adaptation without fundamental reconception.
The Catalog Screening Process
For a large catalog, a two-stage screening process identifies the highest-priority candidates before the full four-criteria evaluation.
Stage 1 — Power dynamic pre-screen: review every title's premise in one sentence. Flag any title whose premise contains a specific power dynamic between two characters. Eliminate titles whose premise is power-dynamic-neutral. This stage reduces a 500-title catalog to typically 50 to 100 titles.
Stage 2 — Engagement data sort: for the titles that passed Stage 1, pull available engagement data. Sort by reader or viewer completion rate and character engagement metrics. Identify the top 20 titles by engagement data. Apply the full four-criteria scoring framework to the top 20.
The Stage 2 output is a ranked list of 15 to 20 high-priority adaptation candidates from a 500-title catalog, produced in two to three weeks.
What Happens After Selection
If you hold existing scripted IP — completed films, TV series, franchise narratives — the vertical remake model is a low-capital entry into the format. You are not creating new IP. You are restructuring existing narratives for a new consumption format, typically through a production partner with vertical format experience.
The selected title's adaptation begins with IP adaptation rights confirmation and the adaptation brief development. The adaptation brief is structured identically to the original series brief: genre thesis, paywall position, visual register, character configuration, and delivery technical requirements. The difference is that the character configurations, central tension, and arc architecture derive from the source material rather than from original development.
The AI-native adaptation advantage: the source material's character design, power dynamic structure, and emotional arc already exist as adaptation material. The character bible for AI generation is built from the source material's character descriptions. The arc map is built from the source material's narrative structure. The pre-production infrastructure build is partially pre-populated by the source material.
Axis AI Studios Perspective
IP holders with large catalogs have the most commercially efficient starting position in vertical drama: the evaluation framework can identify high-priority adaptation candidates at minimal cost, the source material pre-populates the production infrastructure, and the existing audience provides the acquisition cost advantage that original series cannot replicate.
At Axis AI Studios, IP catalog evaluations for vertical drama adaptation potential use the four-criteria framework described in this post. The catalog pre-screen produces a ranked adaptation priority list in two to three weeks. The concept test for the top-ranked title answers the commercial viability question in three to four additional weeks.

FAQ
How Long Does the Four-Criteria Evaluation Take for a 500-Title Catalog?
The two-stage screening process takes two to three weeks. Stage 1 takes two to three days with one evaluator reviewing premise summaries. Stage 2 takes one to two weeks depending on the availability of engagement data for each title.
Does the Evaluation Framework Apply to All IP Categories?
The framework applies most directly to narrative fiction IP: novels, web novels, short story collections, television series, and films with narrative premises. For non-narrative IP categories, the power dynamic clarity criterion is the most useful standalone filter.
What Rights Are Required for Vertical Drama Adaptation?
For web novel IP, the adaptation rights are typically held by the author with the platform holding a licensing agreement. For published novel IP, the adaptation rights are typically held by the publisher or reverted to the author. For television IP, the adaptation rights are typically held by the studio. The IP licensing guide covers the complete rights structure.
