Stupid characters make movies hard to watch
I realize that when you're talking about hayseed gangsters you're not exactly working with atom-splitting IQs, but the scene where the moronic kid breaks the store window to steal the cardboard woman and gets them caught by the cops just makes me groan.
It's a great movie, but all gangster movies are cursed with a few absolute morons who make me want to throw things at the screen. It's as bad as a horror movie where the girl does exactly what she's not supposed to do.
