Iron Man. Thor. Captain America. ...Ant-Man...? Could this movie be the first misstep by Marvel, or will it be their next huge hit?

I'm a huge fan of superhero movies. And so far, Marvel has done a great job with the Avengers, Iron Man, and all of the rest. But Ant-Man? I'm a little skeptical, even after watching the new trailer. Give it a look-see and let me know your thoughts.
