Sex Drive's first 30 minutes may lead one to suspect there's nothing new to be seen here, but it undergoes a transformation once the preliminaries have been dispensed with. John Hughes would be pleased - and so also might Judd Apatow.

Seth Green is uproarious as an Amish farmer who speaks in sentences so passive-aggressive, they're like tiny slaps.

A testosterone-fueled road movie that displays the same Apatow-ian obsessions, and raunch, as "Pineapple Express," "Superbad," and "The 40-Year-Old Virgin."

Remains faithful to a portrait of teens as they see themselves.

Sex Drive offers a limp variation on a hoary old teen-film trope.
