I saw Cars last night and Pixar has done it again! It was a great movie and the animation was fantastic. A movie like cars wouldn't have been possible a couple years ago, because the time spent rendering would have out lasted the time spent writing and modeling. What's the difference in this movie? Rendering reflections requires Ray-tracing meaning you take a ray from your eyes (the camera) and follow what it sees after bouncing off various objects. The time it takes to do this is huge, as I have discovered while rendering my own projects.
Also, I wouldn't have noticed if Jessie hadn't said she heard somewhere that the last couple were not Lasseter projects, but I could tell the humor in this was more adult themed, in line with Bugs Life and Toy Story. Just think about Woody and Little Bo Peep as opposed to Sully and Boo or Mr. and Mrs. Incredible and you'll know what I mean. I would be fun to be a kid and watch these, then grow up and watch them again because the delivery of the adult jokes is so subtle that kids never even realize they're being left out of the fun. I'll be glad to see the movie again because there were things even I missed that we discussed at dinner afterwards.
