Hot Tub Time Machine 2 ★★½

I'm a staunch defender of the first Hot Tub Time Machine, but this unnecessary sequel leaves a bad taste in the mouth. Certainly funny at times, but some scenes drag on for too long, and others trade genuine wit for moral bankruptcy, expecting sheer insanity to do the comedic legwork. (The persistent gay panic vibe frustrates, too.) Shame, but if you liked the first there's at least some value in here - that "nerd" singalong works a lot better in-context than in the poor trailer.
