Utterly idiotic scene ruined the movie (spoilers)
I was enjoying this movie until the dumb scene where Ava does the ritual to get her friend possessed.
Such a stupid, stupid, stupid scene, turning the main character into a complete moron.
"I got possessed and nearly killed a bunch of people, so I'm just going to listen to my airhead friend and get her possessed again and sacrifice a frog while I'm at it."
Completely destroyed any sympathy I had for this character. Talk about stupid characters. Everytime I think I've seen the stupidest character in a movie, a new movie comes along to take stupidity to another level.
