Dance Flick (15)

You don't have to be a moron to enjoy the Wayans Bros' gross-out spoofs, but it would certainly help.

Fans of their Scary Movie and its sequels know what to expect, though perhaps even they will notice here a thinning in the comedy and a coarsening in its misogynist and homophobic riffs. Not an honest laugh in 90 minutes. Mr and Mrs Wayans Sr have an awful lot to answer for.
