How was "The Black Dahlia"?
In mystery stories, I hate those that pull a rabbit out of the hat at the end. This one does that to a certain extent (although the wife and I are arguing just how fair the ending really was -- she claims that it's totally unfair, whereas I claim that you could get most of it figured out with the clues presented to the audience.)
In sum, not a bad way to spend a couple of hours, but nowhere near as good as something like "L. A. Confidential" or "Chinatown."
