I just watched this horrid film 2 days ago. At no point did I think this was in any way good. The only reason I suffered/survived the whole thing was that I was trying to see if maybe it was one of those slow at first and then gets good movies. I was wrong. I spent the last two days trying to figure this movie out. The way it ended, it all made NO sense to me. Then as I was reading other reviews to see if anyone felt the same, or if someone had understood it and explained. Thankfully, someone did explain it. Sort of. It was more of a 'theory', but I'll go with it, since it made sense to me after I thought about it. Basically, Alice goes to the supposed creepy house to finish a screenplay, her 'girlfriend' drops her off and then leaves. Alice starts seeing/hearing weird things in the house. Alice finds a box of tapes and starts watching them. Uses them to write her screenplay. Witnesses a murder on it. Turns out a lot of what we saw, happened in her head. She was reliving repressed events. After, unfortunately remembering the movie, Alice called Rebecca at one point and asked her to look up information on David and Lucy. At the end, when Alice calls Rebecca again to tell her that David is in the house, Rebecca has no idea what Alice is talking about and says "I haven't talked to you in over a week, I've been worried about you." And that leads me to believe that the conversation with Ben didn't happen. For one, if Rebecca hadnt heard from Alice all week, she didn't really tell Alice that Ben was out of jail. Which lead me to believe that Ben isn't really out of jail... And he couldn't have possibly known where Alice is, nor could he have gotten her number.
From what I gathered, Lucy=Rebecca, Alice=David... and Ben seems pretty unimportant...but maybe he plays Davids mom or the one that 'David' thought 'Lucy' was cheating on him with? Who knows.. If you notice, at the beginning of the movie, when they're in the car, Alice has the video camera and is recording Rebecca. At the end of the movie, Rebecca goes downstairs to look for David, she finds only the video camera on the floor and on the tape she sees herself on a bed, just like when Alice first found the tapes and it showed Lucy on the bed and David recording her. There was so much and nothing at all going on in this movie at the same time.
