Year One is a comedy that sets itself up as an epic, but turns out to be an epic piece of shit. It’s 90 minutes of Jack Black playing Jack Black in a funny costume, alongside Michael Cera playing Michael Cera in a funny costume. It’s a movie that consistently goes for the easy joke and still fails. I’m a little baffled that the same man who wrote Stripes, Caddyshack, Ghostbusters, and Groundhog Day wrote this piece of dung. Then again, he also wrote Caddyshack II, so maybe it’s understandable. Unless you’re really desperate to see a movie, or you have an even more infantile sense of humor than I do, avoid this at all costs.
