Pixar has been on a creative roll since they hit the scene. There has yet to be a bad Pixar movie...some are better than others (I'm not a big fan of Cars, for example, though I still find a lot of it entertaining.)
Toy Story 3...which I had sequel-wary concerns about...proved to be another gem...touching, funny, even a bit intense, and utterly charming (though, that said, I hope they don't push their luck by trying to make Toy Story 4...let it go and move on.)
Entertainment Weekly recently ranked Pixar's offerings...my list is different (see below)...yours will most probably be different too. It's all good...like I said there are no bad Pixar movies.
The Neverending Rainbow rankings:
1) Finding Nemo ("...fish are friends not food...")
2) The Incredibles
4) Toy Story
5) Monsters, Inc.
6) Toy Story 3
9) Toy Story 2
10) A Bug's Life
Next year's movie is scheduled to be Cars 2.
