Lets be honest, you probably already know if you want to see Hot Tub Time Machine 2 or not based on the first one, the crude, crass style of humor, and the cast. This is generally the kind of foul-mouthed comedy you either like or you don’t, and it delivers exactly what you expect on that front.
I legitimately enjoy the first movie. It’s hard to claim that it’s great art, but it’s self-aware in a fun way, witty between dick jokes (and I’m certainly not at all opposed to a well-timed dick joke), the story moves along at a good clip, and there’s even a kernel of heart and friendship underneath it all. The second one, however, has none of these redeeming qualities.
