I liked the movie. It was fun; sure, it wasn't Pixar's best movie, but that's not what Cars was about in the first place. For all the people saying Cars and it's sequel are bad in comparison to the other Pixar films, Cars 1 and 2 were never made to be an emotional, life changing film. Cars as a series is supposed to be the fun, easy-going movie of the company that is supposed to be a joyride, kind of like a blockbuster. It is the film where Pixar gets to relax and have a break from making the emotional movies they are known for, such as Up and Wall-E. In this sense, Cars 2 was a good movie.
Cars 2 was fun and exciting, and that's what I go to see movies for: to take a break and have fun from everyday life. Yes, I enjoy complex films with heavy stories, but sometimes films like Cars are needed as simply a break from that. I enjoyed it, and personally, I thought it was good. Come to Cars 2 to feel like a kid again and to just have a good time and you will enjoy this film.
