And I say this as an afficiando of really dumb movies
Premium Rush, aka the movie with bike messengers doing things on bikes and a corrupt NY cop, is not just dumb, but stupid and not at all entertaining dumb. You may try to make fixed gear bikes seem like the great tool that brought down The Man but you will fail. All it needed was a hipster wearing a trilby opening a record store in a deprived area to make it even more dumb.
