Not nearly as clever as the brilliant title may suggest, Hot Tub Time Machine is a fairly silly yet sloppy comedic enterprise. The purposely moronic nature of it leads to some raunchy enjoyment, and the premise involving a time-traveling Jacuzzi allows for some fun comedic situations. The trouble is that the movie shadows our foursome of dudes (John Cusack, Rob Corddry, Craig Robinson, and Clark Duke) too closely. The movie presents intriguing comedic setups but spends inordinate amounts of time dealing with the fractious falling out between the dudes. We spend more time talking about old friendships than we do the sheer possibilities brought about through time travel. The pacing has some turgid moments; it takes too long to reach the magic hot tub. There’s some good humor at first when the guys believe they must follow the exact path they tread before, lest the butterfly effect destroy the future. Then they decide to walk a different path, taking advantage of their knowledge of the future. The movie doesn’t fully take advantage of its own comedic possibilities and settles for lame payoffs, like an end credits sequence inserting Corddry into a Motley Crue video (it’s not funny). There are a few Farrelly Brother-level gross-out gags, but most of the comedy happens around these guys, not because of their characters. They themselves are not exasperatingly funny, so it’s disappointing when Hot Tub Time Machine flirts with fun comic scenarios (an outlandish bet on a sporting game, performing a modern song, the mystery of how the bellhop loses his arm, Duke making sure he will be conceived in the past) only to give up and spend more time with the guys hashing out their years-old squabbles. Enough with the personal growth and reflection. Get back to messing around with the space-time continuum.
