WALL-E is not just Pixar's best movie. It is not just the best animated movie ever. It is the BEST. MOVIE. EVER. Period.
Cars was sub-par and mediocre. It had a basically good plot, but they stretched it out for a good half-hour longer than they should have. Also, I got kind of tired of Finding Nemo after being dragged to it so many times. I mean, I still LIKE it, (especially the sharks. Having sharks portrayed in a sympathetic light is just.. heartwarming for me. Sharks are my favorite aquatic animal.) but not as much as the others.
Having Nemo invade Epcot and replace the epic Tarzan Rocks! didn't help. It would have been better if they had taken Disneyland's route; refitting the old 20,000 Leagues Under the Sea ride for a Nemo ride. Ah, well...
Here's my list:
1. WALL-E (Just.. Perfect. And, even though I'm a guy... WALL-E is the msot adorable robot ever.)
2. The Incredibles (It was the most original superhero movie ever, and the only Pixar movie that really DOES need a sequel. Like, it could involve what they go through now that Supers are back, and when a new generation of Supers - both good and evil - appear. Or something else only Pixar could come up with...)
3. Toy Story 2 (Improved on the original in every way. Better animation, better humor, better everything.)
4. Monsters, Inc. (I always LOVED monsters, and this was a great movie, and possibly their funniest.)
5. Ratatouille (It was good, but a little too... I dunno, artsy to be truly great.)
6. A Bug's Life (I like it, but it was forgettable. But, anything that portrays mantids as heroes is immediately awesome.)
7. Finding Nemo (I liked it, and Bruce, Chum and Anchor are truly awesome, as are Crush and Dory, but I was dragged to it too many times.)
8. Toy Story (The sequel was MUCH better than the first, which is rare.)
9. Cars (Unlike the others, it was only slightly above average fare. It felt like, since this was originally going to be the last film they made with Disney before Disney bought out Pixar, they made it below average just to irk Disney.)
