A movie with a paper-thin premise – two grown men (or man-children – they act like they're six, not forty) who still live with their parents resent each other when they become step-brothers. The two men are played by Will Ferrell and John C. Reilly, and director Adam McKay, who directed Ferrell in his best vehicle, Anchorman, lets them do pretty much whatever they want. It's just these two dopes playing off each other for an hour and a half. It's impossible to defend the movie as cinema, and I think most people would find it extremely obnoxious. But I really like these two actors, and I laughed myself silly at Step Brothers. Besides the two leads, Adam Scott is hilarious as Will Ferrell's d-bag little brother, who, unlike his brother, is a great success. Also Kathryn Hahn as Scott's wife, who becomes smitten with Reilly after he punches her husband. She has the best two scenes in the movie.
