Let me start off by saying i agree with most of what you said. Valid and justified complaints

.
I posted a couple questions about the movie maybe a month ago and i also pointed out the similarity between what david banner was doing and the lizard...very strange that either the screen writer or ang lee chose to incorporate this.
I really am getting kind of tired of that type of argument, that 'You can believe a guy can turn green and throw around tanks, but you can't believe childhood acquaintances wouldn't meet each other up again at the same job?' As you said, there are things we expect to suspend our disbelief for, and other things that should be much easier to believe. If you go by that argument, well why not just make spider-man able to fly and have heat vision? I mean after all, if you can believe he got spider-powers, why can't he just fly? Very stupid argument.
I was also disappointed by this. In my post with questions i wondered what exactly the point was of that mushroom cloud...was it even a gamma bomb? In my opinion, they should have kept the origin of the hulk being created from a gamma BOMB.
I really don't understand why they couldn't have just called him rick. They didn't even have to give him a last name, just call him rick. Then if they need him for any future movie, *then* give the last name jones.
I really never thought about this until you mentioned it, but you're absolutely right. When watching the movie, you don't get a sense that the hulk is a psychologically different being that just wants 'to be left alone.' Hopefully in the second movie we will see isntances where banner says he hates the hulk and vice versa.
Bit off topic, but did anyone else think it was kind of stupid in T3 when he shot at all those policemen and then did a scan and read 'body count 0' or whatever? I mean yes he's supposed to be a good guy, but the terminator is not supposed to save every human life at whatever cost.
Though not as much bothered me about the movie, i do think you made a lot of good points. I was confused at some parts of the movie (e.g. why did they let david banner go and talk with bruce when he was all chained up?). Hopefully the second movie will do a better job explaining stuff and we'll get to see more hulk from the beginning.
