There's a difference between Step Brothers and Baby Mama. Step Brothers is not up to par with the best work of the Will Ferrell-Adam McKay writing team, but it is not like Baby Mama in the sense that it has made me lost faith in the brand. Many critics seem to not know the difference. Bob Hope and Bing Crosby made 7 films together. Would critics have given this film a bigger pass if Will Ferrell and John C Reiley's film were called Talladega Nights II? What I'm getting it is I thought this film was plenty funny and certainly inventive enough. In fact, I stayed in the theater and watched it twice. The big stars of the film are not John C Reilly and Will Ferrell but Mary Steenburgen and Richard Jenkins for holding down straight faces and being convincing as a loving dad and a loving mom of such silly characters. You could insert the characters played by Jenkins and Steenburgen into something like Cheaper by the Dozen or Gilmore Girls and it would still pretty much work.
