No it's not debatable he's a good filmmaker. I dislike the LOTRs films but Peter Jackson deserved the Oscar because he made a great film I just dislike it. Going back to Zack Snyder Dawn of the Dead is his only film I can sit thru and enjoy from start to finish and it's still nowhere near as good as the original. Snyder isn't my cup of tea doesn't make him a bad filmmaker. Uwe Boll is a bad filmmaker ironically I find some of his films fun because of that but he's a bad filmmaker not Joel Schumacher.
