Most Boxing movies are Dramas...
For a change of pace, here's a pretty good Boxing movie that's a Rom-Com... well more like an Indie Com-Rom (more Comedy than Romance, but very Indie). If you're an Adam Carolla fan, then I'm sure you've watched it and liked it... but even if you're not a fan, the movie is still pretty good. It's cutesy, but not in a bad way.
