Hulk to me has always been a under Developed Character with a seemingly bottomless amount of stories within him, Sadly though many times we've been forced to see many writers go against the whole concept of Hulk, which is Science Fiction esqe and instead have to be told the Billionth time how hard it is for Bruce Banner.
Hulk is a character that gets better the farther the writer goes out on a limb and is different and even a bit wild in the realm of Science Fiction..Planet Hulk proved it through a very gritty and far out idea.
Saddly though Hulk will always play a second fiddle to the higher arcs of heroes (Spider-man Captin America)
Not to say these are not good characters, but we must admit that the hulk has alot more allowed to him. The Hulk for one could kill, Go crazy, Fight other Heroes without stretching to far off. It seems the fate of Hulk is in good hands for now. And it seems keeping him out of the Civil War might actually help him out where it hurt others.
My only advice to the writers if they could see this would be to let Hulk be THE HULK...let him dominate some teams of heroes. Let him run major havoc on the fantastic four, Maybe put Grimm in the hospital. Just don't make him the Monster of reasoning..Hulk never Reasons...Hulk Smashes.
