Terrific movie, with just one gaping flaw... (spoiler)
I saw this on Netflix last night. I had never heard of it before, and it certainly deserves to be better known. There was just one big problem I had with it: The scene with O'Reilly, Lucy and Pam was unbelievably contrived. Lucy just happened to have found out about her boyfriend's death just before she arrived home at that particular moment, and she just happened to be the type of person who mixed fantasy and reality in the way that she did and so (inadvertently) said everything that would have convinced O'Reilly that William Martin was real. That was WAY too much to swallow.
But that aside, it was an absolutely perfect film.
EDIT: Sorry, forgot to put (spoiler) in the subject line!
