A hilarious, unsettling satire of suburban politeness, Greener Grass has my vote for this year’s unforgettable sleeper comedy, on par with films like Napoleon Dynamite or Wet Hot American Summer. But co-writers/directors/stars Jocelyn DeBoer and Dawn Luebbe have turned out something so much tighter than either of those films. Greener Grass is so relentlessly funny that I expect you’ll soon be hearing its lines traded around between film buffs. (“Do the children play soccer on graves? I haven’t noticed that before.”) My only criticism is in the time-honored casting of a large woman with greasy hair as one of the film’s more obvious villains, but then again, it’s suburbia—so really, they’re all villains.
