You don’t watch a movie called Hot Tub Time Machine expecting any sort of high-brow humor–and if you did it’s all on you because there wasn’t any be found–but what you did get was three actors thrown in the pretty bizarre situation, and their idiosyncratic ways of coping and adapting.
When you think about it, it could actually be the Citizen Kane of hot tub time machine movies.
The first time around apparently appealed to more people than just me, because Lou (Rob Corddry), Nick (Craig Robinson) and Jacob (Clark Duke, which can’t be the name he was born with) are back in Hot Tub Time Machine 2.
This time around it seems that the guys have, predictably, fraked up the future. This really bothers someone (whom I am willing to bet is either Nick or Jacob), who then attempts to kill Lou. Nick and Jacob get Lou back into the time machine, and attempt to stop the would-be killer.
It goes without saying that they bring their own special brand of incompetence to the proceedings.
