Until “The Hangover 2” hits theaters sometime next year, comedy lovers will be itching to find a male-bonding movie as juvenile and riotous as the original Las Vegas romp of last year. The closest they’ll get so far this season is with “Hot Tub Time Machine.” Despite its similar comedic elements and disregard for levelheadedness, the blast-from-the-past flick doesn’t have more than obvious jokes in its arsenal.

Like “The Hangover,” “Hot Tub” features four friends who find themselves on the biggest misadventure of their lives. Instead of Sin City, however, Adam (John Cusack), Nick, (Craig Robinson), Lou, (Rob Corddry), and Adam’s nephew Jacob (Clark Duke) are vacationing at a Nevada ski resort where the three middle-aged friends used to party back in high school.

Bored with their lives, the trio wants to recapture the glory days when they were all younger, dumber, and full of aspiration. Their trip takes a bizarre twist when the foursome climbs into a mysterious hot tub and are magically transported back to the year 1986 for one more chance to relive their adolescence.

Not only do the boys travel back in time, they also transform back into their teenage bodies (with the exception of Jacob who is already a teen). Since Jacob hasn’t technically been born yet (and since he begins to flicker like Marty McFly in “Back to the Future”), they guys realize if they don’t do exactly what they did 24 years prior, Jacob might disappear and never be born.

The whole idea of the “butterfly effect” is used loosely throughout the film as Adam, Nick , Lou and Jacob search for the hot tub repair man (Chevy Chase in a wasted role) who can get them back to the present day (think Don Knotts in “Pleasantville” without the personality) and run around the resort trying to remember specific aspects of their past so they can keep the future intact.

Most of “Hot Tub” is a one-joke homage to the 80s. It has a number of hilarious moments (especially when Robinson is involved), but wears out the nostalgia after a while. Yes, cassette players and Jheri curls have their place in a movie like this, but why fixate on the obvious?  It’s one thing to create an 80s-inspired world and build a comedy around it, but “Hot Tub” relies too much on the references to get the bulk of its laughs. Legwarmers are funny, but not that funny.
