Specifically animated films? As Dreamworks has released some trash over the years (Norbit being the worst offender).

Best:

the how to train your dragon movies, Megamind (at a stretch)

worst:

this has made me realise there's a lot of animated Dreamworks films I don't care about: The Bee Movie, Cars, the Croods, The Kung Fu Panda films, the boss baby etc etc

I don't mind the Shrek films. #2 is pretty good.
