Not funny at all
I didn't think this would be a great movie, but I thought it would at least be funny. It has a great cast and the director, directed great episodes of tv, especially some of his Community episodes.
This movie is just flat and boring. Nothing stands out. None of the jokes were great. It really felt like a lame, tv movie. It either needed to be a dark comedy and go in a crazier directon or it needed to be more fun like Christmas Vacation. It's a forgettable movie.
