About RankThatMovie

RankThatMovie is an independent movie-discovery project. Most trend feeds simply rank by raw popularity, which rewards whatever is loudest on a given day. We do the opposite: we try to separate a real signal from noise, and we publish exactly how we do it.

How the Radar score works

Every title in our pool is scored from 0 to 100. That number is our own composite, built from four inputs and one penalty. It is not TMDB's rating, IMDb's rating, or anyone else's.

Smoothed quality. A raw 9.0 from 40 votes is not the same as a 9.0 from 40,000. We apply a Bayesian shrinkage toward a global mean so thinly-rated titles can't game the top of the list.
Momentum. We reward titles that are genuinely climbing this week, not ones that peaked months ago and never left the charts.
Freshness. A gentle recency curve so newer, relevant releases aren't buried under evergreen classics.
Reach. A log-scaled popularity term, so mainstream awareness counts but can't dominate on its own.
Suspicion penalty. When a rating pattern looks statistically unusual — a very high average resting on a suspiciously small or lopsided vote base — we dock the score and label it. We never call anything “fake”; we simply flag that the signal is less settled.

Trust labels

Alongside the number, each title carries a plain-language trust label — from Stable signal through Slightly unusual and Unusual pattern to High volatility. These describe how much confidence the underlying data supports, so you can weigh a score in context.

Curation

Our collections aren't scraped lists. Each one is a rule we wrote — “strong quality, clean trust signal, modest buzz,” for example — applied live to the current pool, with an original note explaining what it's for. As the signal shifts, so do the lists.

Where our data comes from

Film metadata, artwork and streaming availability come from official, licensed sources: The Movie Database (TMDB) API, with availability powered by JustWatch. We link only to official, legal platforms. We do not host third-party artwork, and we do not link to or embed pirated content of any kind.

What a Radar score means

The score is a 0–100 summary, not a rating out of 10 rescaled. These are the bands we use ourselves when writing the one-line verdict on a title page:

78–100 — a strong signal with a settled vote base behind it.
62–77 — a solid pick; momentum is real but the evidence is thinner.
45–61 — middle of the pack; worth a look if the genre fits you.
0–44 — quiet, very new, or carrying a trust penalty. Treat as provisional.

The same film shows the same number everywhere on this site — homepage, catalogue and its own page all read from one calculation. If you ever see two different numbers for one title, that is a bug and we want to hear about it.

A worked example

Take a title rated 7.7 from about 580 votes, with high current popularity and a release date inside the last month. Bayesian smoothing pulls the raw 7.7 toward the global mean because 580 votes is a modest sample, giving a quality component near 0.66. Popularity maps onto a momentum component near 0.90 on a fixed logarithmic curve — not a ranking against whatever films happen to sit next to it. Freshness adds a small amount, and the suspicion check finds no unusual rating pattern, so nothing is deducted. Weighted together those land at a Radar score of 74.

Known limitations

We would rather state these plainly than have you discover them:

Scores depend on TMDB data. A film with very few votes can move sharply as votes arrive; that is why thin samples are flagged in the verdict text.
Popularity is a TMDB metric influenced by page views and search activity, so it reflects attention, not quality. It is deliberately a minority of the weight.
Streaming availability is regional and supplied by JustWatch. “No verified availability” means we could not confirm it — not that the film is unavailable.
The suspicion check detects statistically unusual rating patterns. It cannot prove manipulation, and an unusual pattern is sometimes just an unusual audience.
Age suitability follows the official certificate where one exists. Where none exists we fall back to conservative keyword signals, which are cruder.

Methodology changelog

Current version: v3.0.

v3.0 — momentum is now derived absolutely from popularity on a fixed curve. Previously it was a percentile within whichever set of films was being scored, which meant one title could show a different number on the catalogue than on its own page.
v2.1 — trust/suspicion discount added to the composite score.
v2.0 — Bayesian smoothing of audience ratings introduced.
