Greatness
Artistic, historical, formal, critical, and durable cinematic achievement.
How to use GCML
The Field Guide.
How GCML works, what the numbers mean, and where to go next.
01 · What the numbers mean
Read the score before the rank.
Engagement
How powerfully a film holds attention and rewards the viewing experience.
Ease
Lower-friction viewing: clarity, pacing, duration, intensity, and the practical conditions a film asks of its audience.
Total
GCML Total is the combined recommendation score created by the 40% Greatness / 40% Engagement / 20% Ease model. It is not simply a pure measure of which film is artistically greatest.
Worked example · Canon rank #1
Parasite
9.6 Greatness × 40% + 10.0 Engagement × 40% + 9.6 Ease × 20% = 9.76 Total.
The arithmetic is reproducible. The Greatness, Engagement, and Ease scores themselves remain editorial judgments.

Open →TonightGenerate recommendations for the time, attention, pace, emotional tone, genre, discovery preference, and occasion available now. Tonight uses situational fit; it is not another name for Ease.
Open →Double FeatureBegin with an anchor film and receive a meaningful, discovery-oriented companion rather than an automatic sequel or franchise pairing.
Open →CollectionsBrowse curated thematic and editorial routes through the canon.
Open →Change the LensExperiment with alternate Greatness, Engagement, and Ease weighting philosophies without changing the official canon.
Open →Canon InsightsExplore composition, chronology, external-list membership, and the structure of the canon.
Open →Cinema PassportTrack viewing geographically through the countries represented by films marked Seen.
Open →DiscoverUse additional personal and exploratory pathways through the canon.
Open →03 · How the canon is built
External reference, then direct curation.
Sight & Sound · IMDb · AFI
These are external reference lists. Their membership and ranks provide context, but they do not directly determine GCML Greatness, Engagement, Ease, or Total scores.
230 films outside all three
These films were added through direct curation to extend the canon beyond the 483-film distinct Big Three union.
713 is this edition’s editorial boundary, not a claim that cinema has a fixed number of essential films. Why 713?

04 · Reading the data
Context matters, but not every field is a score.
Awards
Contextual metadata only. Awards add no scoring points.
External ranks
Sight & Sound, IMDb, and AFI ranks provide context and reference. They are not inputs to GCML scores.
Tie-breaker
Equal Totals are ordered by higher Greatness, then higher Engagement, then title.
Spoiler-Free Premise
A setup-only, spoiler-conscious description that avoids later-act revelations.
Why It Belongs
The concise editorial case for a film’s inclusion, grounded in craft, influence, form, or emotional power.
US content ratings
Known classifications are retained. When a reliable US classification is absent or uncertain, the film is marked Not Rated rather than assigned a guess.
Ease
A practical measure of viewing friction, not intelligence, quality, or artistic importance.
Seen
Records a viewing and updates Cinema Passport. Tonight excludes Seen films unless Include rewatches is on; enabling it makes them eligible, not guaranteed results.
Loved
Helps Tonight learn related tastes once at least three films are both Seen and Loved. Loved without Seen does not train these preferences.
Want to Watch
Gives a saved film a modest preference among already strong Tonight matches; it cannot override exclusions.
Not for Me
Always excludes that exact film from Tonight, even if unseen or marked Rewatch. Broader taste patterns require at least three Seen + Not for Me films.
Rewatch
Contributes a preference only when that film is Seen and Include rewatches is on. Seen films without Rewatch intent can also qualify.
My Film ▾
Contains Want to Watch, Loved, Not for Me, and Rewatch.
