Absolutely Dreadful.
I just watched Cars and Cars 2 back to back. The original Cars is weak compared to the other Pixar films but compared to other animated films it is still a good film.
Cars 2 though, I can't believe I'd ever say it about a Pixar film but it was complete garbage. Mater is quite possibly the worst character Pixar have come up with and some idiots over at Pixar thought it was a good idea to make him the main character of the movie.
He's not funny, I didn't feel sorry for him, his voice his annoying, hillbillies are annoying and he should never have had such a large role. McQueen was not that significant in the movie, Sally was hardly in the movie.
The story was a poor generic dated spy story with cliché characters. Poor music, poor villain and it was not funny.
The movie was a commercial to sell toys. There was no heart or soul in this movie.
This movies has a 6.4 because it's a Pixar film, I'd love to know what the score would have been had it come from someone else.
