I just finished the Planet Hulk series(bought the hardcover collection on Amazon) and I am totally back into the comic book lover's field. I haven't really got into a comic since about 1990-1992(the year when X-Men drawn by Jim Lee hit).
I am certainly awaiting the results of WWH. But I am not really interested in buying the individual comics as of right now, more into the collections.
In reference to Hulk having some intelligence instead of the "Hulk SMASH" mentality. I really think it has to do with the simple fact of the matter that Banner is never truly gone. He is and will probably always will be a constantly existing part of the Hulk. I doubt they can truly exist without eachother. Just think, the gamma radiation basically brought all the anger, frustration, and aggression that Banner had inside of him to surface. Took him from frail to average human to nearly limitless physical strength. I would have to say that now it is a reverse. Great physical prowess with some hint of intelligence/wit. I like it. Maybe I am wrong? But I like to think I am going in the right direction.
