Ummm... I didn't get it...

**********SPOILERS FOLLOWING - DO NOT READ ANY FURTHER IF YOU HAVEN'T SEEN THIS MOVIE YET*******************














Here is my take on the ending and I hope this helps.

*A reviewer said that David and Lucy were not real. I believe they were the former occupants of the house, but we do not know what actually happened to them. When Alice found the tapes her fragile mind concocted the troubled relationship between the two to mirror her own troubled relationship with Ben. The fact that the first tape revealed Lucy's pregnancy fueled Alice's obsession with Lucy and David. The last "tape" which showed David drowning Lucy was a part of Alice's hallucinations. That's why Rebecca did not see the tape of the killing when she sat down to look at the video camera at the very end.

*The necklace with the name "Lucy" belonged to the real Lucy as did the dress and the high heels. Alice lost herself completely and was identifying with the Lucy in her imagination. She had been a victim of Ben's jealousy and anger and so Lucy also was a victim of David's jealousy and anger.

*The two phone calls between Alice and Rebecca never happened. Rebecca told Alice that she had not heard from her all week. She had no idea that things had gone horribly wrong. So the bit about Rebecca finding information about David Woods who drowned his wife and his mother reporting them both missing was a fabrication. I suspect it was a red herring to make viewers think that David was probably still in the house and stalking Alice by this point.

*Alice identified with Lucy as both were victims, but she gave her imaginary David some of her characteristics. The obsession with filming their love interest (it is implied that Alice and Rebecca were lovers) and the bit about David having had a mental breakdown when Lucy had tried to break off their engagement. Alice had a mental breakdown when Ben tried to kill her. David's obsession with Lucy's supposed infidelity mirrored Ben's obsession, but his fragile mental condition is also similar to Alice's.

*It's implied that David's obsession with Lucy mirrors Alice's obsession with Rebecca, even though they haven't experienced any difficulties yet. At some point before going to the house Alice filmed Rebecca sleeping and made the comment about looking like an angel. Rebecca had just finished reading through Alice's screenplay. She had read about David doing the same thing and also about David's jealousy and rage. Rebecca was seriously creeped out when she saw the tape and the full impact of what she had read hit her and then the movie ended.

*When Alice received the phone call from Ben and he declared that he was going to leave her alone I believe that phone call also fueled her fantasy about David's mother coming in and saving him from suicide (hanging). It was after the phone call from Ben where he said he was staying with his mother that Alice then came to the "conclusion" that David's mother saved him from hanging and then covered up his crime to protect him. She believed he had stayed in the house and then she lost herself completely in the Lucy persona and thought that David had tried to drown her too.
