Well, the cast has SO many good actors... and i think Edward is a much better option for Bruce Banner than Eric (IMHO).
I think this movie is gonna rock!
I like A LOT the plot, hope it works fine...
AND... i think the new "smaller" hulk is much better... my first opinion was "What's up with that hair?"... but after watching it a few times (yeap... like 3 or 4 XD) i really like how it moves when Hulk shouts and runs...
I think this is going to be a much better movie, specially because of the villain.
As Stan Lee once said : "The hero, is only as good as the villain he fights. It's the villain what makes a good hero, not the hero itself"... or something like that XD
