Plotline Score
A 0–100 rating for a series, split into the three things it measures: how highly its episodes rate, how evenly it holds that level, and whether it climbs or slides. The three are always shown, never just the total.

Which seasons are worth it
Plotline analyses every episode of a series — where it declines, how steady it is, whether it lands its ending — and prints the numbers behind every verdict, so you can disagree with it.

What the engine works out
Where it falls off
The season after which quality drops and never recovers — printed with the averages before and after, and which seasons fall below it.
Episode ratings, charted
A rating curve per season with touch selection, and a score grid that puts every episode of every season on one screen.
Shelves you won't find elsewhere
Shows That Never Slip. Knows When It Peaked. Worth the Wait. They Stick the Landing. Brilliant and Baffling. Not genres — groups derived by analysing every episode, each with its measurement spelled out.
Works on a plane
122 fully analysed series ship inside the app. No account, no sign-up, no subscription — the scores and the verdicts are there in the first frame, with no network.
It says when it can't say
When a series has too few rated episodes to support a conclusion, Plotline says so and says why, instead of inventing a softer verdict.
Films, on their own terms
A film has no episodes, so it gets no Plotline Score — claiming one would be inventing it. It gets box office instead: budget, revenue and ROI, alongside franchise timelines and the filmographies of its cast and director.
