The premise of Novocaine is fun: what if you don't feel pain? What follows is a cartoonish, surprisingly violent, film, as Jack Quaid's Nathan tries to rescue the girl of his dreams.
There's a little bit in the trailer that doesn't seem to have made the final edit, where his friend warns him that he's not indestructible. Unfortunately movie physics pushes that way beyond credibility.
It doesn't quite make the most of its central idea. Yet approach it like Quaid is playing a Looney Tune and there's enjoyment to be had.
