What Is Review Bombing?

Review bombing is when a group of people, usually coordinated online, floods a film, show, or game with a burst of negative ratings in order to drag its score down, often for reasons that have nothing to do with the work itself. It is a specific, documented tactic, and once you know how it works, you can usually spot it.

How does review bombing work?

The mechanics are simple. A large number of one-star reviews arrive in a short window, frequently from people who have not seen the film, sometimes from a few individuals using many accounts, sometimes organized on social media or message boards. Because most rating systems are just an average, a concentrated burst of the lowest possible score can move the headline number fast, especially before many genuine viewers have weighed in.

The tell is not the low reviews themselves. Every film gets some. The tell is the shape and the timing: a spike of the lowest possible rating that arrives suddenly and stands apart from the rest of the curve.

Why do people review bomb?

Rarely because of the movie. The consistent finding across documented cases is that the trigger is something outside the work: a casting choice, a filmmaker’s or an actor’s politics, a culture-war grievance, a business decision, sometimes just trolling. Films with female leads or diverse casts have been frequent targets. The reviews often use inflammatory language and say little about the actual film, because the actual film was never the point.

That is what separates review bombing from ordinary criticism. Criticism engages the work. A bombing campaign is aimed at the score.

How do the platforms fight it?

The major platforms treat review bombing as real enough to build defenses against, which is the clearest evidence that it exists.

Rotten Tomatoes stopped accepting audience reviews before a film’s release in 2019, after a wave of pre-release bombing, and introduced a Verified Audience Score that counts only viewers confirmed to have bought a ticket, so a coordinated push cannot pass itself off as the crowd. IMDb runs an automated system that detects unusual voting activity and applies an alternate weighting to suspicious votes, which is why a film’s displayed score is sometimes lower than the raw average of its votes: the platform is already discounting something. These systems are imperfect. One known limitation is that IMDb’s detection leans on one-star votes, so some campaigns switch to two-star ratings to slip past it.

How can you tell if a film was review bombed?

You look past the number at the shape, and it takes a minute.

  • Check the lowest bin. In an honest distribution, scores taper toward the extremes, so the very lowest rating is one of the smallest groups. A spike that stands above its neighbors at the floor is the fingerprint.
  • Compare raw to weighted. If a platform’s displayed score is below the plain average of its votes, its anti-brigade system is already at work.
  • Weigh the volume. A small film with a few hundred votes is far easier to swing than a blockbuster with hundreds of thousands.
  • Check the timing. A sudden burst of one-star ratings, especially early, is worth a second look.

The short version

Review bombing is a coordinated attempt to lower a score, usually over something other than the film, and it leaves a shape you can learn to see. The best defense, for any film, is the same: look at the distribution, not the headline, and when in doubt, watch it and judge for yourself.
