Cars 2

There are several factors that made the Pixar film "Cars" not as successful as the rest of its blockbuster brethren.  One of which was such a wooden lead in Owen Wilson's Lightning McQueen. Audiences (mainly children) really liked Larry the Cable Guy's wisecracking, hick, tow truck.  The other was the somewhat lackluster story of a sports hotshot who learns to slow down and enjoy life.  Something with a little bit more action and pizazz was what I felt like the story needed.  Thus, both these issues are addressed in "Cars 2" with the focus shifting more on Mater the tow truck, and the film switching gears (hahaha) to a spy thriller flick.  Not only that, but with the main character status now thrust upon Mater, the new side-character is a James Bond-esque, tricked-out, gadget car named Finn McMissile, voiced by Michael Caine.
The plot essentially puts our Nascar Wilson into a world grand prix, giving the animators an excuse to flesh out (so to speak) the world that these sentient cars live in, integrating three distinct human cultures (Japanese, Italian, and English) with a very automotive twist.  But back to the story at hand, Mater gets mistaken for an American spy car, and Michael Caine and his female tech car put the hapless, completely clueless, tow truck on a wild espionage ride involving a bad car mafia and the race Owen Wilson is in.
And while it is not as amazing as "Up" or "Toy Story 3," it is still a great film, leagues better than its predecessor. But what do you expect, it's from PIXAR!

Also, moral of the story was kind of better handled in Kung Fu Panda

Mater is now Kamen Rider Fourze because he has these weapons:
