I don't read a lot of comics, and most of those I do are from DC or indie publishers. However, I recently picked up Old Man Logan just because I liked the art (that's the only usual reason I read any comic books at all).
The storyline, however, perhaps unsurprisingly, confused me a little. In particular I wasn't sure how The Hulk ended up as one of the central villains of the piece - my understanding was that in the Marvel stable he was generally treated as a hero, albeit an exceptionally unreliable one.
I presumed this was just some alternate timeline stuff, which would be supported by the device in the comic that its version of Banner got an extra-large dose of radiation, driving Banner to insanity. Although it's interesting to note that all the other characters in the comic conform to their traditional roles, which raises the question of why Millar chose the Hulk to act as a major antagonist.
However elsewhere on the net - including here - examples from Old Man Logan are given as canonical answers to queries about Hulk and the X-Men. If it's set in an alternate timeline, surely it can't be canonical?
So what's the deal here? Is my misunderstanding down to my inexperience of the genre? Is the comic considered canon or not? And if it is, how did the Hulk end up to be so nasty?
