Step Brothers isn't the funniest Will Ferrell movie but it's such an enjoyable viewing experience because the chemistry between he and John C. Reilly is great. The amount of epic one-liners in this film alone make it worth watching. Is the plot ridiculous? Is the acting over the top? Is it crude and offensive? Yes, yes, and hell yes but that's Will Ferrell. It isn't his best movie but it's still a must see for Ferrell fans.
