Each guy deals with his own measly emotional problems. Derrick is upset because he can't get oral sex from his wife. Jackson's new girlfriend once dated his own father. And Brian can't get his mother to hug him. That's about the depth of the story.
Nobody gets pregnant or comes down with a disease.
We basically wait for these four guys to stop whining and find girlfriends. Our impatience is understandable. The Brothers wastes some real potential. This is the first movie in ages with African American leading characters playing doctors, lawyers, and young professionals. They dress well, don't take drugs, and behave reasonably politely.
