Opening five years after the events of the first film Lou Dorchen and Nick Webber have become very successful thanks to using other people's ideas. Then, at a party, Lou is shot in the groin and later dies. His son Jacob and Nick drag him to the time machine and they hope to travel back in time to stop the shooting... they actually end up in the future; a time when their lives are somewhat different. Evidence suggests that the killer is from this time period; the trio will have to find the killer before he goes back to commit the crime. They suspect former friend Adam Yates who was bitter after missing the trip in the first film that led to Lou and Nick's success. They find his son Adan Jnr, and he joins the search. In what follows they get into a number of sticky situations.

This sequel was rather disappointing; there were some genuinely funny moments but too many gags relied on the fact that Lou is a thoroughly unpleasant character... he is a bully who more often than not gets away with it. Most of the gags are fairly crude without the wit to be funny. The film is clearly inspired by numerous other time travel films, which are inevitably name checked by the characters. The cast do a decent enough job with the material. Overall this is far from a must see but if you like your comedies crude you might enjoy it... I'm just glad it only cost me 50p and that went to a charity!

You might have overly loved the first Hot Tub movie and it might exceeded your expectations. Therefor you might have very high expectations of this one. But this one just drags the hilarious along and does not care too much on making sense. In fact, you could say it spits on anything that tries to explain what is going on or is trying to give it a certain quality at all.

What this succeeds in doing, is being gross, mean and infantile. Now if that is what you're expecting going into this, you'll have a lot of fun. But remember: this is not about quality, and I cannot stress that out enough. It's about a group of people gathering together and taking the p... as the British would say (translation: having fun). Take that with a grain of salt and it'll help enjoy the movie. I know I was entertained enough, with just watching one sketch following another. Remember: this is just a movie (with no scientific explanations to the weird things that are happening).

Lou Dorchen (Rob Corddry) is now the jerk, hard-partying, head of Lougle after stealing all the tech advances. Nick Webber (Craig Robinson) has stolen all the songs to become a music star mogul. Jacob Yates Dorchen (Clark Duke) is haunted by the knowledge that Lou is his father and struggles to find his place. Lou is shot in the balls and the guys try to travel back in time to stop the murder. Instead they travel 10 years into the future. They assume that Adam shot Lou but they find his son Adam Yates Steadmeyer (Adam Scott) instead. Steadmeyer is a straight-laced guy about to marry Jill (Gillian Jacobs). Also Jacob is the big success in the future while the other two are struggling.

Rob Corddry overpowers this movie with his jerk character. The chemistry is off-kilter. Instead of an idiot sidekick, he's the villain lead. He's actually hateful and horribly unfunny. Although there are a few scenes that are so ridiculous that it's somewhat funny. Otherwise, this is an unfunny mess.
