I don't read comic books, I'm the casual Iron Man post credits scene invested in the MCU kind of guy. So I'm not well versed with the source material itself.

So I'm just curious as to why would fans be so interested with that World War Hulk movie they're talking about? I mean I get the fact that the Hulk deserves his own movie again, now that there's a new actor for him, which is the very talented Mark Ruffalo. Yet I've also come across some discussions that some people would disagree with the storyline because it's a swift transition to Banner's story arc or something, and Banner still needs more stories to be told other than the World War Hulk story.

So what's really going on here? Can anyone clarify this for me?
