I'll just snag what I said about it from Twitter here:
What I love about White Men Can't Jump is that isn't not even your ordinary sports movie. They're not underdogs, they don't miss the big shot, they don't even win the championship at the end. It's just about two guys scraping to make a living with basketball being a hustle.
The girl doesn't even stay at the end, she literally leaves after another one of Billy's fukk ups. Basketball doesn't even unite the two opposite players. They just learn that even if they don't like each other, they can use each other to make money.
It's a classic.
