Wow, you just saved me alot of typing...your thoughts are the same as mine on the films.Cars and Cars 2 were my least favorite Pixar movies.
The Incredibles was first place for me (I saw it, uh, 6-7 times in the theater... *blush*), due to animation (which emulated Rankin-Bass live-action animations from the 70's, to my eye), great voice work, tight script, and the unique music; and Wall-E and Up are probably close follow-ups. Even with as much as I loved The Incredibles, the bookends for Up just blew me away, and the fact that Wall-E goes 20-25 minutes telling the narrative without dialogue is just an incredible feat on its own, I just didn't think the rest of the movie (once they get to the spaceship) is nearly as strong.
That isn't knocking Toy Story 1-3, I consider it one of the few times in cinema when sequel movies didn't fall flat but kept the quality coming.
Finding Nemo was also solid, but it didn't resonate with me as much as the others.
I'm seeing Brave today. The reviews have kind of spoiled it for me (basically, it's supposed to be "really good if it were Dreamworks or Disney, but not quite up to Pixar quality"), but I'll see about that....
Bugs Life gets kind of a bad rap, I think. Most reviewers have put on a lesser tier, but I found it endearing, honesly. I really liked it... and better than Ants.
EDIT: Saw Brave. It was an enjoyable movie but didn't really stick to me like the best Pixar movies have done. The whole "second act" caught me off-guard, not sure how I feel about it since it changed the tone of the movie as per the previews. While the squabbling between mother and daughter was complained about by some critics for being "too much of the same old," it was only a little too much for me -- actually that interaction seemed pretty close to home with the "mother daughter" relationship when puberty hits and there are control issues.
There was NOTHING special during the credits. Pixar was the company that the other animation houses emulated as far as putting stuff in the credits, and this time the credits were just... credits. Boring. really boring. There is a short scene at movie's end, that is a natural continuation of something in the script, so hang out for it.
Definitely better than Cars. I'm not sure whether it was better or worse than A Bug's Life. I'm inclined to think the latter was a slight bit better. I'm just used to Pixar movies having more texture.
Except I haven't seen Brave yet.
