I just saw Ratatouille. Excellent. The thing with Pixar is that they produce a product that excels in all it's various parts. They are never satisfied with doing an acceptable job, they do an exceptional job. In everything. The writing, voice acting, and music are all excellent, but I think the graphics stole the show. Never have I seen graphics that good before.
I shouldn't say graphics, because that implies that it's simply a matter of rendering power. The images of Ratatouille are art. I believe you could take a random frame from a pixar movie and odds would be good that it would be impressive by itself.
The short before the movie proper was also very good.
Ratatouille gets 1 out of a possible 5 Ron Perlmans. Congratulations!
