Metacritic Metascore — How Review Aggregation Works

Metacritic converts every review to 0–100 and averages them with secret per-critic weights — preserving intensity that Rotten Tomatoes flattens, at the cost of transparency.

What the Metacritic Metascore Is

The Metascore is a weighted average of professional critic reviews, published by Metacritic (founded 1999) for films, TV, music, and games. Reviews in any format — stars, letters, percentages, prose — are converted to a 0–100 scale, weighted, and averaged into one number with a traffic-light color.

Where the Tomatometer asks “what share of critics approved?”, the Metascore asks “how much did the important critics like it?”.

What the Metascore Ranks

Metascores rank entertainment titles — films, TV seasons, albums, and video games — by intensity-weighted critical opinion. Color bands communicate at a glance:

  • 61–100 — green (“generally favorable” to “universal acclaim”)
  • 40–60 — yellow (“mixed or average”)
  • 0–39 — red (“generally unfavorable” to “overwhelming dislike”)

A separate user score (0–10) aggregates registered-user ratings.

Core Inputs Used by Metacritic

  • Curated critic reviews — from a selection of respected outlets per medium; a minimum number of reviews (typically 4+ for games, more for films) is required before a score publishes
  • Score conversion — each review’s grade is mapped to 0–100; ungraded reviews are assigned values by Metacritic’s editors
  • Critic weights — outlets and critics carry different, unpublished weights reflecting stature and consistency

How the Metascore Is Calculated (High-Level)

  1. Every curated review is converted to 0–100 — a B+ and a 3.5/4 both become numbers, prose-only reviews get editorial assignments.
  2. Converted scores are combined in a weighted average, with each critic’s weight applied.
  3. The result rounds to the published Metascore; the score typically stabilizes after the release-week review wave but can drift as late reviews arrive.

Conceptual model: Normalize every critic onto one ruler, then take an average where famous hands on the ruler count more.

Update Frequency

Scores update as reviews are curated in — most movement occurs in the days around release, with slow drift afterward.

Known Limitations and Criticisms

  • Opaque weights — nobody outside Metacritic knows how much any outlet counts, making the score unauditable
  • Conversion distortion — mapping a letter grade or a prose review to a precise number embeds editorial judgment in the data
  • False precision — a Metascore of 74 vs. 76 implies distinctions the input data can’t support
  • Industry pressure — game publishers have tied bonuses to Metascore thresholds, a documented case of a ranking distorting the thing it ranks

Where the Metascore Is Used

Metascores are used for:

  • Consumer purchase decisions, especially in gaming
  • Publisher contracts and developer bonuses in the games industry
  • Awards-season and year-end “best of” tabulations
  • Retail and platform merchandising (scores shown in storefronts)

Summary

The Metascore is the weighted-intensity school of aggregation: convert everything to 0–100, weight the critics, publish one number. It preserves nuance the binary Tomatometer discards — and hides the recipe, which is why it is simultaneously the more informative and the less transparent of the two giants.
