Looks good! I have a theory about the ending of this film, and this trailer kinda makes me think it's going to be true. I did have a little squeal thing going on when I saw that little flash of JGL.
They're going to reboot this franchise in a few years though, I don't know how they'll go about it. As awesome as the first two films were, looking back on them, they're definitely a version of Batman for the civillians kind of thing. The newer Marvel comics films have found a better balance between comics and what the general public will accept seeing on screen, so I wonder if they'll go in that direction.
