i think Green Latern could have been done better...
What I think is that, they should take off from this trailer and make a whole movie...
To me the green lantern character sucks. He has zero depth, a full length movie is too much time to drag out his story. The same goes for the Hulk, which explains why all of the hulk movies have bombed.
I would like to see a full length movie about Galactus, but I know that it won't happen.
