What do you think of this twist? SPOILER
***SPOILERS***
I saw this for the first time last night and thought this twist would have been interesting...
When Graham is telling Ann that he was a pathalogical liar. Wouldn't it have been interesting if instead of fantasizing about these women he recorded he actually murdered them. His pathological lie would be that he only videotapes them. Cynthia would already be dead and he was going to kill Ann.
I don't know, just an odd twist to the movie. I was actually expecting something like this when he was spilling his beans. As messed up as Graham was it wouldn't have surprised me. I guess how it was made made the ending even more surprising.
