We're in a fertile time for comedy, especially the small bites of improv seen on Comedy Central and Adult Swim. David Wain (Wet Hot American Summer) does a pretty good job of bringing this sensibility to long form. Paul Rudd and Jennifer Aniston star as an unemployed New York couple who, while on the road, chance upon a commune and decide to try the make-love-not-money lifestyle. The supporting cast is an all-star team of players from such fare as Reno 911! who excel at humor that combines goofy gags with subtle observation of modern tics (Wain delights in passive aggression and oversharing). Among the killer turns is Justin Theroux as a shaggy shaman who takes Aniston for an amble down his nature trail. But what keeps Wanderlust from achieving transcendence is a fuzziness in the writing of its two leads. Rudd does some great riffing (especially his hillbilly dirty talk), but ultimately the sum of Wanderlust's parts is greater than the whole.
