10 Horror Movies That Tricked You Into Rooting For The Monster

10. The Faculty

An easy way to appeal to our most base biases? Take the monster and disguise them as a seemingly harmless, even adorable character. Furthermore, it's a doubly effective gambit if you make them an attractive woman.

And that's precisely what Robert Rodriguez did in The Faculty, as it's revealed in the third act that the monstrous alien queen has actually been hidden in plain sight the entire time, taking the guise of cute, naive high-schooler Marybeth Hutchinson (Laura Harris).

Her disarmingly affable demeanour led most audiences to immediately write her off the suspect list and actively root for her to survive, such that when she eventually disrobed and revealed her grotesque real form, it was a genuinely jaw-dropping surprise.

Marybeth's utterly non-threatening presence and apparent romantic interest in Zeke (Josh Hartnett) made her a total blind spot for most viewers, compelling them to cheer her on for most of the movie. Oops.
