Don't let the innocuous title fool you. Family Weekend is a subversive little comedy in which a tightly wound misfit of a teenage girl, fed up with watching her family spiral out of control, subjects her parents to an extreme intervention.

The unconventional dysfunctional family has now become a Hollywood convention. It is familiar to a fault.

For a long while, director Benjamin Epps goes for breakneck farce; at its best, this is a batty mixture of family-values editorial and teen spoof.

We're sitting there, trapped. An angry little teenager's yelling at us. And we're not having any fun at all.

The script, by Matt K. Turner, is loaded with contradictions, its hollow flirtation with subversion amount to airplane pablum.
