One other thing that I really disliked about this movie, is instead of revealing the plot gradually throughout the movie, they just thrust it all in our faces without explaining anything and then supply a 5 minute segment of grainy footage at the end in a kind of 'you sat through this and here's your reward' kind of way. It's like the writer thought, 'hey people won't understand what the hell is going on' and then just threw together an attempt at making things appear more coherant. Very poor. It's a good concept for a movie but executed poorly through bad writing.
