The only real hole I thought in character development was: (Spoiler warning)

The kid realizes his father is a phony, and yet has the stones to get a shotgun and blast away some goon in his front yard while little Sally is selling Lemonade down the corner, then, (after rescuing his father from certain doom), he tosses the gun down and gives his dad the cold shoulder?

I mean, to me, he isn't going to grab that gun and help out unless he's embraced the fact that his father is a phony criminal. I don't think he had time to do that from the moment he went inside to when he grabbed the gun and came out firing.

And if he has embraced that fact, why is he now giving his dad sh** for being a professional bad-ass? That was a hole, IMO.

EDIT: Popcorn movie tidbit for ya (SPOILER WARNING #2): This movie reminded me of JOE DIRT when Clemm pulled some heroics and the mafia saw him on TV and came to pepper him with bullets.
