Showtime's Brotherhood gets a third season
For those who don't watch, Brotherhood is the story of the Caffee brothers, who are members of an Irish mob family based in Providence, Rhode Island. The characters are loosely based on Winter Hill Gang member Whitey Bulger and his ex-politician brother William.
I haven't seen the show, but in doing some reading about the series it seems like an Irish family variation of The Sopranos (many critics have compared it to the latter. Some found in closer in tone to The Wire). It may start doing better since the ending of The Sopranos has left a void for more crime drama.
I do wish more networks would get behind the idea of keeping a show on the air if it doesn't get the best of ratings but rather it gets critical acclaim. That might have saved shows like Arrested Development.
