Anything that has CGI in it that comes out in IMAX pretty much must be SEEN in IMAX to be most thoroughly enjoyed. CARS 2 is well worth it. The amount of awesome detail the Pixar folks gave to each of the four countries our heroes travel in (Japan, France, Italy, England) and their customs and the look and feel of the real places, yet mutating them just slightly so they fit into the CARS universe was phenomenal! (And yes, there are some Japanese toilets that do seem that complicated!)
While a spy story with loads of great chases, mistaken identities, covert ops, secret plots, super cool gadgets and more, it still centers around the main theme of the friendship between McQueen and Mater. Also a big lesson that despite what you are given by life, you can choose to make more of it and never judge a book by its cover.
The story was solid, clues given along the way if you keep your eyes peeled. I did feel sorry for the lemons, though I will say from personal experience that Hugos were totally dependable cars and served me well, so not sure why they picked on them. 😛
Be on the look out for in-jokes or homage bits. Several places in other Pixar films show up (the restaurant in Ratatouille among them). The pre film short based on Toy Story was darling!
Overall it was a super fun film with loads of great sequences and will leave you with a happy heart when it ends. (No extra stuff after the credits, though the background stuff during the credits was most amusing and some of it totally neat.)
Rating: 4 out of 5 (Hubby said it was Worth Full Price of Admission)
