You people have too much time on your hands! I picked up on a lot of these things without thinking too much, but, as Jason pointed out, we're still left with the question whodunnit? This was the biggest thing for me. I like to know this sort of thing. All that time line stuff is pretty cool now that I've thought more about it, but I like movies with good ending and I didn't get that here. There was too much unanswered.
