2. Hulk Works Best As Part Of A Team
Perhaps this notion doesn't apply in the the comic book medium, but in the movies this point rings absolutely true: the Hulk is a character who, cinematically, at least, works best when he's surrounded by other characters. Why? Because with each and every one of the points I mentioned above, these simply aren't problems for the majority of other superheroes in the Marvel Universe. To make the Hulk a problem for
these superheroes, though - that's genuinely interesting from a narrative perspective. When Bruce Banner is just one member of a team, after all, there's not an entire movie riding on the decisions that he chooses to make. But throw him in as a dangerous element, use him as part of the plot (like Whedon did in
The Avengers, and rather crucially) and you heighten his impact without exposing the flaws that come with a standalone adaptation. The Hulk is, ultimately, most interesting because of how other character
react to his presence and the inherent danger of having him around.
The Avengers totally proved that.
