Editing can really bother me when watching a movie.
Like I was watching Invictus, and the part near the end where it's basically three minutes of slow motion. I wanted to gag and stuff my cock in the person's ear who edited that shit. You make use slow motion as tension. It's supposed to build up, and explode like a guy cumming on his first pair of tits. When I watched the credits I was looking for the editor, I was gritting my TEETH,"this better not be Clint. Clint is better than this." Thankfully it wasn't. Jesus Christ those two-three minutes of Invictus were awful.
