10 Great Horror Movies Ruined By Their Twists
4. The Forgotten (2004)
There's nothing worse than a trailer giving away too much of a movie. If you see Tom Hanks standing at the crossroads without a beard, why bother seeing Castaway? That being said, after watching a trailer you should have some idea of at least the type of movie that is being advertised.
From watching The Forgotten trailer, you might believe that you're in for a story about a government conspiracy, or a brainwashing cult, or perhaps just run of the mill mental illness/repression resulting from grief. These would all be sensible guesses and each version might theoretically end with a satisfying payoff.
In reality, this movie is about aliens. Aliens who have the ability to delete (some) peoples memories and also Photoshop their pictures and re-wallpaper their houses and stop their children from ageing or possibly go back in time and also bullets don't hurt them and they can look like humans sometimes.
Note to filmmakers: just because an audience doesn't see something coming doesn't make it a good twist. It's just as likely a case of bad filmmaking.
