First of all, I thought it was FANTASTIC. Second of all, if no one has noticed... everyone who hated Ang's version is going to love this, anyone who loved Ang's version will hate it end of story. I think we all should have seen that coming.
Now as for the testing part that a few of you are freaking out over.
"Ross explains that Banner was part of an early experiment to create super soldier serum, but the funding was running out. In the eleventh hour of the project, Banner was so certain of his research that he tested it on himself – that’s when everything went to hell."
It personally seems to me as he is talking about Bruce's father. Think about it, he was working for the military in Ang's, they wouldn't let him test on anyone, time was running out, he was running out of funds, so he injected himself with it. Not to mention it was most definately something to create a super-soldier, as it had to do with regeneration, and strength. They may have just added the term "Super-soldier" as a term to tie it with Captain America, which I remember hearing rumors something would relate to him in this movie anyway. To me it's much better than him just showing up out of no where or seeing him on the news in some dopey weird cameo.
Plus we already know they plan to use Hulk in the Avengers movie.
Sounds to me as if its a vague sequal to the last. I mean, come on, Brazil? His father testing it on himself? Very reminisent. Although I could be wrong and it is just Banner testing on himself then so be it.
