I don't want to defend Waid particularly as I hated his run, but I don't think the statement is all that indefensible.
The context of it was that Banner/Hulk believed that Tony Stark sabotaged the gamma bomb test and essentially was the entire reason that Banner became the Hulk in the first place. All of the bad stuff that had ever happened consequently - including the deaths of Jarella, Betty, Caeira etc, but also his life being ruined repeatedly for years, being hounded constantly etc etc - were thus on Stark's head. All of that guilt and fear and loathing that Banner/Hulk had carried around for years as a result of that fateful day was transferred onto Stark. I think it's pretty reasonable that he would be ridic angry at that point.
Whether one chooses to believe that it would make Banner/Hulk literally as angry as during World War Hulk is, as far as I can see, somewhat immaterial. The simple fact is that the writer of the scene clearly envisioned the Hulk as extremely angry to even make the comparison, which is more than enough evidence to debunk carver's stance that Hulk was completely calm.
Lol...Nothing to break about. It's a battle on the mental plane. A place where Thanos has control and he isn't even using his own power for this. He is hooked up to a machine iirc.
Just read the issue. The entire "fight" takes place in a virtual reality which houses the spiritual consciousnesses of Thanos, Hulk and Banner. Thanos is able to manipulate and control the rules of the virtual reality at will, including weakening the Hulk's consciousness. Banner uses his smarts to briefly much with Thanos's control over the VR, but ultimately his intellect pales into comparison with Thanos and consequently Thanos dominates the mental exchange (though it is directly attributed to being an intelligence feat rather than a physical one).
Judging by the end of the issue and solicits for the next two, I don't think we are going to get an actual, real, physical fight between Hulk and Thanos at all. Talk about an anti-climax...
