WTF!... (spoilers)
What the crap. Mr. Collins was my favorite character. Screw that ending. I totally saw it coming when he gave her the hug when she was pounding on the door, and I almost turned it off right then. What should have happened was someone else was tormenting her, and Mr. Collins should have saved the day. That would have sufficed, but no. They had to go and make the only likable character in the movie the psycho. Naturally.
