Spider-Man was ok, but the underwhelming use of Venom was a disappointment. Even when I was a little kid, I thought the Superman movies with Christopher Reeves were kind of retarded because the special effects were fake-looking & it was so cheesy.
Obviously, Superman is still the most awesome hero ever. However, my close second choice of powers would be that of The Green Lantern.
I think computer graphics have gotten to a point that could do the character justice.
This trailer for the upcoming movie I saw on Fasthack looks pretty good. Of course, I would improve upon it- by adding more black to the suit, instead of it being all neon green.
