I dont' know....Up, The Incredibles, Ratatouille equally.

Finding Nemo, easily.

I also liked a lot Monsters Inc, Toy Stories and Incredibles. Have not seen Up but really want to.

My god, I can't believe how overrated is Wall-E.

Yes, it was brilliant...in the first half. Then it changed the pacing, humor...everything. Sadly at that point I was yawning at the theater

No love for Cars?  Geez people.  I've lost faith in Humanity and it's future.

Car's was good - no Pixar film is bad as such - but it's nowhere near as good, particularly in terms of narrative and character complexity, as their best films.

The post credits does include the line that perhaps made me laught louder than any other Pixar joke:

"Hey, they're just using the same guy's voice over and over again!"

Finding Nemo.

But omg at Ratatouille, Toy Story, Toy Story 2 and A Bug's Life.

Up and Wall-E were good but something was missing to make them awesome.

I haven't seen Toy Story 3, The Incredibles and Cars yet and I don't remember Monsters Inc.

Toy Story 3

Finding Nemo.

I've never seen a stronger message about family love. :)

It might just be Toy Story.

I still haven't seen Wall E, Up, Ratoulllie, or Toy Story 3 yet though.

I don 't like pixar,I'm not 5 yrs old anymore. lol

Probably Finding Nemo, or the Incredibles. Either of the two, but they're so different it's hard to choose.
