Strange Wilderness has three bad comic ideas for every good joke, and it botches many of those, too, thanks to slack comic timing and a nonexistent grasp of storytelling basics. But just when the flop-sweat stench is about to become unbearable, Strange Wilderness stumbles upon an uproarious, laugh-out moment, and suddenly it's tolerable again for another few minutes.

By far the funniest part of Strange Wilderness is the trailer for "Harold & Kumar Escape From Guantanamo Bay" that's running before it.

The result is a slacker comedy that goes slacker by the second, trying hard to be rude and crude but suggesting an old John Candy-Dan Aykroyd movie with bongs and more swearing.

What rankles isn’t the gross-out humor or the verbal non sequiturs, which are expected, even welcome, in this sort of movie. It’s the smug sense of entitlement -- that of intoxicated dweebs tittering endlessly and obnoxiously at their own supposed cleverness. “Harold and Kumar Go to White Castle” is the gold standard in this genre. Strange Wilderness is a counterfeit bill.

Despite the presence of funny guys such as Zahn, Garlin, Justin Long and Jonah Hill, along with veteran character actors Ernest Borgnine, Joe Don Baker and Robert Patrick, the movie fails to be even passably funny.
