Is Marvel's Closest Equivalent Actually Pixar?

Marvel's seemingly unstoppable block of superhero flicks has spawned more than a few imitators and comparisons among studios that work in the genre. But is the best comparison actually animation icon Pixar?

In response to this post on what to make of the glut of superhero movies headed our way in the next few years, commenter Pessimippopotamus suggested that Marvel's ability to blend the superhero genre with other genres — whether space opera, heist capers, or spy drama — actually had its best analogue not in DC, but in Pixar:

The only way to escape superhero/comicbook movie fatigue would be to transcend the genre. Marvel now represents not just comicbook movies, but quality blockbusters. Remember how Hollywood is constantly inundated with terrible CG cartoons? Pixar transcended the cartoon "genre" by showing everyone that CG technology is just a medium, and that they could make any kind of story into a movie. Marvel is doing something very similar. It's taking comicbook source materials and molding them into movies of different genre. It's a smart way to make sure that people don't feel genre fatigue. However, Marvel still risks franchise fatigue, especially since it's juggling several IPs at the same time. But it's proved that you don't need to follow the franchise closely to enjoy a new Marvel movie with Guardians of the Galaxy, so I'm very hopeful.

Also, here's a thinking that I see pop up frequently: Marvel is the new Pixar.

What do you think? Is the comparison of the two movie-makers use of genre-mixing as a way to breathe new life into their movies a useful one? What areas of overlap and difference do you see? Give us your thoughts in the comments.
