If you're a fan of Fran Kranz, Zachary Levi, or Kenan Thompson, you will enjoy this film. The three guys vibe off each other really well, their dialogue is quick and pithy, and the physical humour is well played. (And if you just like Levi for his looks, there's quite a treat in store for you.)
The heart of the movie is the journey of three friends and there is actually a really sweet (and funny) moment in the film when their friendship is tested, and one friend does whatever it takes to heal the rift. However the film is far from sentimental. It's fast paced and packed with jokes. The humour is silly, the plot takes some bizarre turns, and of course some of the jokes are a little cliched. But, it's all really good fun. And there are even a few fresh gags in there (as someone who watches a lot of this type of film I am impressed when I see a joke I haven't before).
It's a wiener, not a chef's special, so it probably won't fill you with satisfaction. But it is definitely one fun and tasty morsel.
