10 Horror Movie Reveals So Bad You Almost Walked Out

7. The Lipstick-Face Demon - Insidious

A bit of a controversial choice here perhaps, with James Wan's Insidious.

Now, there are absolutely some brilliantly effective, chilling moments earlier in the film - most notably when the Lipstick-Face Demon suddenly appears behind Josh (Patrick Wilson) totally out of nowhere in the middle of a scene.

But that early glimpse of the demon only further proves the virtue of brevity in horror, because once we get a more prolonged look at the guy, he becomes near-impossible to take seriously.

In the film's finale when Josh enters the purgatory realm known as The Further to rescue his son Dalton (Ty Simpkins), we get a considerably better look at the Lipstick-Face Demon, who through repeated exposure makes his resemblance to Star Wars' Darth Maul ever-more clear.

Wan shoots the whole sequence like a goofy funfair haunted house, as runs entirely counter to the genuine creepiness of the demon's fleeting earlier appearance. And in turn, Wan sinks the whole movie in the final stretch.
