This movie begins in the year 2015—that is the year 2015 in the altered universe created by Nick (Craig Robinson) Lou (Rob Corddry), and Lou's son Jacob (Clark Duke) in Hot Tub Time Machine (2010). An unfortunate accident causes the gentlemen to seek out the tub to go back in time to prevent the accident from happening. In their attempt they find themselves in the future, learning that they must fix events in the future to fix the present, as the present day accident was caused by someone who came back from the future. Confused? Well I can't blame you. I understood it completely, but I personally can't stand these time travel movies, whether serious science fiction, or comedy. I guess this movie actually spoofs on just how convoluted it is, and they even mention several films where this happens such as Back to the Future (1985), The Terminator (1984), and the TV Show Fringe (2008-2013). In the first movie the time travel concept was kept simple, and the humor was enough to outweigh the time travel concepts. I quite enjoyed the first one. This one, not as much. A decent comedy, and I suppose the plot was clever—time travel is just a topic I never really care for.
