Step Brothers (2008)

Co-written and directed by Will Ferrell's long time collaborator Adam McKay, Step Brothers is firmly rooted in the 'adults as adolescents' school of comedy and stars Ferrell and John C. Reilly as grown men who never left the nest and become the titular 'step brothers' after their parents marry. The two share a room, feud then become friends, then feud again before ultimately reconciling. Though it has a few funny moments and gets maybe a little better towards the end, for the most part it's not funny, not pleasant, and lazy. I saw the 'unrated' version but suspect the theatrical cut is just a slightly less vulgar version of the same. Everyone involved in this movie is capable of better. *1/2
