Overall, I think Cars was great. Pixar has done a great job and I have to say that it was stunning. Cars has more soul and makes you realized that life is not all about winning...it is about the friends we make and experiences we have along the way. Life is a highway.
Anyway, I've really liked all Pixar movies. To me, they each have had strong points.
A Bug's Life: Great Characters and music
Finding Nemo: One great tear-jerking movie
Incredibles: Wonderful story
Well done Pixar.
