There's some charm to The Radiator Springs 500½, but nowhere near enough. There are hints of good ideas–like a Western showdown motif at the beginning–and some of the failed gags should have worked–a car who comes along to do the cymbals after a pun. Oh, right, it's a Cars spin-off cartoon short. Forget to mention that part.
Anyway, there's nothing cohesive about it. Half the short is the good car (voiced by Owen Wilson, who must have been busy because he has almost no lines) racing against these bad cars who have no respect for the town. Then the town cars are on this idyllic anniversary drive.
There's an effective junk yard sequence towards the end, but otherwise it's tepid and without any excitement. Springs's greatest stylistic influence appears to be video game cut scenes. Whoop-de-doo.
It might get points for being harmless, but why give points for being harmless?
