10 Awful Horror Movies That Threw Away Brilliant Premises

10. Truth or Dare

Paranormal thriller Truth or Dare opens with Olivia and her friends playing the titular game, but little does Olivia know she's taking part in a ritual, tethering a demon called Calux to everyone who participated. Calux can take the form of anyone and force Olivia's friends to say or do anything, and if they refuse to play, they die.

With a premise like that, the filmmakers could've concocted a plethora of petrifying scenarios since the players can be forced to confess any unforgivable sin and perform any horrific act. One of the players is even dared to burn a woman alive, showcasing how the game turns innocent people into killers to save their own skin.

Sadly, Truth or Dare was a major misfire. Although it has a few issues, the main problem is the villain's design. In human form, Calux is always depicted with a badly rendered CGI smile. So, when Calux forces the participants to slay each other or themselves, it's impossible to take anything seriously every time the camera cuts to the demon's Joker-like grin.

When the smile isn't as pronounced, Truth or Dare looks quite creepy, indicating director Jeff Wadlow shouldn't have bothered with the special effects at all. Removing the digital mouths wouldn't have made Truth or Dare a masterpiece, but it would've stopped it turning into an unintentional comedy.
