I was expecting much worse, but it ended up actually being funny! I figured it would be stupid (and it was), but it definitely had plenty of very comical moments. Crispin Glover probably had the funniest role in the movie in a minor role, it's nice to see him in movies again, I've always liked him as an actor. Hot Tub Time Machine was kind of the same level of low-brow hilarity as The Hangover, only not as clever. But I did find it funny that there is a sub-plot involving Red Dawn, as there was a Red Dawn thread here last week. Coincidence? Or are the Soviets slowly starting to invade my life?!
In the end though, as "above averagely" funny as Hot Tub Time Machine was, I kind of wish they just did a straight-up spoof of 80s ski-lodge movies that didn't involve time travel. Those movies are insane enough to begin with.
