The First Deadly Sin

I recently watched this movie only because it was on my high def station and it "looked" pretty good, but after waiting over an hour to become interested in it, it ended with a confusing and ho-hum climax. Sinatra sleepwalks through the entire movie and looks completely bored. Faye has one of the worst roles in movie history. Can someone explain this ending to me sometime? On second thought, don't bother. If you love Frank and NYC movies from the 80s, this might work for you, but only if you don't mind a story that never really achieves liftoff. The Dunaway role is such a waste of her talent, and him calling her "kiddo" in every scene kind of creeped me out.
