Demand
6/10

Heated Rivalry pushed Rachel Reid's backlist to #1 US romance per Forbes and Publishers Weekly, validating that single adaptations move books; BookTok drives heavy adaptation-discussion content but mostly in-list/TikTok form, not as a dedicated habit.Heated Rivalry Becomes No. 1 Romance Book In The U.S. After HBO Max SuccessHeated Rivalry Breaks the Ice - Publishers Weekly

Whitespace
4/10

Multiple direct competitors already exist — PageToScreen.com tracks 142 adaptations with faithfulness scores, BookToMovies.com and IMDb lists cover the same need; the app angle is the differentiator, not the data layer.PageToScreen — Book to Film AdaptationsSearch Adaptations — Find Any Book-to-Movie Connection | BookToMovies

Monetization
4/10

PageToScreen monetizes via Amazon/streaming affiliate commissions rather than subscriptions; no evidence of paid willingness in this niche, and romance/fantasy readers skew price-sensitive.PageToScreen — Book to Film Adaptations

Longevity
6/10

Book-to-screen pipeline is structurally durable (Hollywood/streamers keep mining IP) and queer/fantasy/romance adaptations are accelerating, but the data is perishable — streaming availability URLs, cast changes, and faithfulness scores require constant curation.Heated Rivalry Is Driving a Surprise Book Publishing Boom

Feasibility
7/10

Aggregator build is tractable — Goodreads ratings and TMDB/streams data are open, but ongoing editorial work to maintain faithfulness scores, cast details, and scene-difference notes is non-trivial labor.PageToScreen — Book to Film Adaptations
