Serious plothole (spoiler)
**WARNING** Contains spoiler.
In the part where Paul is searching on his computer for information about "fallen" star Vanessa Carver, don't you think that, in addition to stumbling upon her website, there would have been some hits about her suicide? The character was supposedly a popular actress at one time and surely, there would have been something there about that. It just seems unrealistic that someone searching for information on someone else, especially if they are infatuated with that person as Paul was with Vanessa in this movie, would miss something like this.
I otherwise enjoyed the movie, a nice slow buildup to a climatic ending.
