alan,you really should have started your spoiler tag a sentence earlier.I'm sorry you didn't like this movie,but theres something about DePalma-if you got a roomfull of his fans together what one considered his best film someone else would be sure to consider his worse.For my part,I think this...

I'm sure there must be more,but have only watched once.Anyone else notice any?
