Sex Drive (2008 Sean Anders & co-scr)

Again, completely inadvertently, we conclude a trilogy of films about the adolescent experience which began with GABAG and continued with Gregory's Girl. This is the depressing American version, a film of two halves, one rebarbatively crude (was this strain of 'humour' all There's Something About Mary's fault?), all cocks, balls and tits; the other really rather funny. Without doubt the scenes with Clark Duke and James Marsden work the best - my favourite moment is Marsden looking for his 1969 GTO and doesn't even bother to stop his motorbike, just gets off it, then pulverises the garage. The Seth Green / Amish moments aren't as funny as they think they are. Showdown with doughnut man also funny.

Josh Zuckerman and Amanda Crew are a colourless couple.
