huh, I always forget about ratatouille, but I think its because its the only Pixar film I didn't see at the cinema and didn't leave that much of an impression on me
As for me, while most of my friends give me wierd looks for it, it has to be cars, I just really enjoyed it from start to finish, and adored a lot of the little touches, like the mountains shaped like cars, the little "beetle" cars as insects and so on.
However I didn't enjoy cars 2... it just felt like they wanted to do a whole other spy movie but the marketing guys said "but cars merchandise sells so well!", which it does, I've worked in retail enough over the last few years to know that. Wierd part is if they just did the world championship part, made that the movie I'd probably have loved it
I'd never call any Pixar movie bad, but the one I enjoyed least was The Incredibles, which thankfully most of my friends agree on too unlike my enjoyment of cars. I can't place why, I saw it at the cinema with all my friends and we all came out of it feeling... well nothing. All the way through I was expecting that special something to hit me as all Pixar movies do at times, yes even cars 2 and ratatouille, but nothing. I was just left with a nothing opinion on it and having a not very entertaining time at the cinema. Each to thier own it just didn't click for me
