Megamind > HTTYD. They're both awesome, though. And then there's Shrek, Madagascar, Kung Fu Panda, Monsters vs. Aliens, Chicken Run, Shark Tale and The Croods. I'd say they're doing okay!
Admittedly I don't think many of them have the most incredible stories, but I tend to be more in it for the laughs than the dramaz when it comes to animated film.
I do agree that Disney rock the 2D animation world, though. I've yet to see anything seriously compete, and that includes everyone's precious Studio Ghibli. I just love Disney's 2D epics (and not-so-epics).
