Because it's Del Toro. And he's a geek, he's one of us, and he loves monsters like we do. So everyone's gonna be all over it. I love the creature and mech design but I couldn't get behind the fights, even in 3D it was just these bad shots of the fights. Only a few times when you can see them fairly well did I really feel impressed.
If anything I'm more impressed with seeing the new Godzilla from Gareth Edwards, who also did the film Monsters, which seemed like a precursor to doing Godzilla. Monsters was alright, as it was more survival and story driven, but I can't wait to see the new Godzilla.
I had no idea what Monsters was about before watching it, but ended up enjoying it quite a bit. It had a District 9 feel to it. I definitely can't wait for Godzilla after seeing it.
