This strength grows with anger thing, is not as extreme as so many many more out there.
But I don't like those either. I love Wolverine, but I hate it whenever he's portrayed as some unbeatable, ultra-cool badass. I love Batman, but can't stand it when they write him as completely unflappable and elitist to other heroes. I thought Superman lifting a continent made of kryptonite was one of the dumbest things I'd ever seen.
Just cause the Hulk isn't the only victim of this kind of thing doesn't make it any easier to swallow. I always like my ultra-powered heroes to be about even. It keeps things balanced and interesting. When a hero is given an instant win clause like the Hulk's "unlimited strength"; I lose interest immediately and can even start to dislike the character if it persists long enough.
Cause the trouble is, the Hulk DOESN'T just have "unlimited strength". If all that happened was that he got stronger, that'd be fine, since other forms of attack could still be used against him. But it seems like he also gains the power to circumvent the laws of reality. Physical strength should not give you the ability to break someone's hands on the astral plane when it's already been established that that can't happen.
But nope, the Hulk's SO strong now, that he can just do that for some reason. If it doesn't bother you, then fair enough. Personally I can't stand it; but that's a personal thing. I know some people DO like to feel that their favorite character is unstoppable, but I've never really been that way.
