This doesn't bother me one bit, and I'm confident Marvel made the right decision based on every other decision they've made so far being the right one. I'm sure this will get a few riled up, but I'm not much of a fan of his work to be honest. Sure I loved Shaun of the Dead and Hot Fuzz, but it wasn't the fast cut-scenes that made me love them. I loved them in spite of that crap. And I'm apparently the only person on this board that wasn't blown away by Scott Pilgrim. I enjoyed it well enough, and I'll admit that if Scott Pilgrim were shot "conventionally" it probably would have been crappy, but if I never see another movie by this guy I won't be disappointed in the least.
I'm not saying he would have made a bad Ant Man, but I was never stroking my wang in anticipation either. And if this turns out to finally be the "bad" Marvel movie (of the Marvel Cinematic Universe era, not counting crap like Ghost Rider), eh, it's Ant Man, I'll get over it I'm pretty sure. If it were, say, Dr. Strange...then I'd be upset. But as good as Irredeemable was, I just can't develop much of an attachment to a character I have *never* given a fuck about. And I have faith that Marvel probably knows what they are doing if they felt the need to kick this guy off.
