I've skimmed through the comments people left. I can't believe how many complaints there were about this movie, about unanswered questions and lack of horror-ness.
Doesn't anyone like the good old leave-you-thinking movies anymore? I LIKED the fact it wasn't a typical horror movie. It made it more believable, and therefore more scary (or creepy, at least). The fact that questions were left unanswered just added to that touch, in my mind. Seems like the people left clueless just weren't trying. I thought it was easy enough to see the house's personality and preference and why it chose certain people to take. It liked Ellen. It took her daughter out of jealousy. It took women who made Ellen jealous by having affairs with John. And by Rose Red, it was insane.
Sure some scenes went fast and I missed something and I was confused..but I had it figured out by the end of the movie. All a matter of expectations.
