Four guys go back to 1986 by some Russian energy drink called Chernobly spilling into the electronic console of a hot tub at a ski resort. Suddenly, everyone's wearing neon colors and Poison is playing. John Cusak says, "I hate this decade...we had Reagan and AIDS" but he hooks up (almost) with a cool reported from 'Spin'. Chevy Chase is a mysterious repairman who warns them about the butterfly effect, so they try to do exactly like they did back in the day, but of course that screws up. Crispen Glover is a one-armed bellhop and there's a time-changing squirrel. I would have liked to see more clashes of decades. Frankly, I don't miss hair metal or anti-communist hysteria, but I actually enjoyed this and laughed my arse off.
