The cg films that have worked for me are the ones with "old school movie" and "theatrical stage" literate plots, even if metaphorically:

Pochahontas
Anastasia
more recently:
Cars
Ratatuille

and especially Robots, my all-time favorite.

The above are all "animated films" from end to end; dramas with cg to make them seem real....probably the films not really known for CG such as King Arthur, Jurrassic Park, etc.

I thought the Balrog was spectacular; disliked the rest of that mess. Read the book.
