Uwe Boll has sworn off many things. He's sworn off Michael Bay (who isn't far behind him mind you) and challenged him to a boxing match, he's sworn off his critics by silencing them with........ nothing at all.
No doubt he physically knows how to make movies - but I've watched all his movies out of morbid curiosity - and they're total shit. Dungeon Siege, less shit. I first thought that because he has created such a name for himself that everything he does is automatically panned, but it's not the case. Still, he makes me laugh.
