Step Brothers (2008)

Brennan Huff (Will Ferrell) and Dale Doback (John C. Reilly) are two grown men still living at home with their single parents. When Brennan's mom (Mary Steenburgen) meets Dale's dad (Richard Jenkins) and the rest, as they is history, the stepbrothers constant competition and jealousy strain the newlywed's relationship. An unlikely truce begins when they discover equal hatred for Brennan's overachieving little 'bro' Derek and the two become inseparable. In desperation, Dale's dad delivers an ultimatum: they've got one month to get a job and grow up.

Step Brothers is a never-ending joke that stops being funny shortly after it's told. Ferrell and Reilly are funny; their chemistry together even funnier, but this film is dull. Gratuitous language and meanness pervade what could have been. Don't get me wrong, they are funny--what's not funny about a 40-year old clinging to under-roos, grilled cheeses, and tree houses--but this gets old fast.
