Dumbledore: "Now, it's great that you've been saving the school and all Harry, but unfortunately your grades have been a tad low, and, well... perhaps Gandalf could explain it better... hit it, Gandalf!
Pixar's got my vote. I think it's generally agreed that Pixar's more recent films have, on the whole, not been as good as their earlier offerings (and they've been making far too many sequels, thanks to their overlord Disney's demands), but that doesn't change the fact that most of Pixar's pre-2010 films are masterpieces.
To be fair, DreamWorks has some very solid movies as well. But if stacked side by side, I'd argue that DreamWorks has fewer great films than Pixar—and Pixar's worst films still aren't as bad as DreamWorks' weakest.
