10 Horror Movies That Keep Tricking Viewers

10. Bodies Bodies Bodies

In Halina Reijn's satyrical whodunit, a group of vapid Gen-Z friends decide to party in an opulent mansion during hurricane season. When the wi-fi and lights go off, they play a murder-in-the-dark game to pass the time.

However, the murder game gets a bit too literal when one partygoer, David, winds up dead, his neck slashed with a sword. Believing there's a wolf in the fold, it isn't long before everyone is at each others' throats, leading to further bloodshed. When Bee and Sophie are all who remain, there's no doubt one of them is the initial culprit.

Or maybe not. 

When it comes to slashers, there tends to be one simple rule: somebody must be the killer. Despite that, Bodies Bodies Bodies flips the script, revealing that David slashed his throat by accident, meaning the massacre that followed was for nothing.

Since this trope goes hand-in-hand with the genre, it's impossible not to accuse every character, especially when everyone behaves suspiciously and acts hostile to one another. Although it's annoying to watch the group accuse the innocent, viewers will feel ashamed when they realise they were doing the same thing.
