Showtime Finally Finds Its Signature Hit?

Showtime has been trying for its own "Sopranos" for years. Even when it comes up with a decent show, like "Sleeper Cell," it can't seem to get any attention. The closest it has come has been to id itself as the gay channel with "Queer As Folk" and "The L Word." Reviews for its new crime drama "Brotherhood" have been a bit mixed (I haven't watched my advance tape yet), but Variety just gave it a rave review. "This is the jewel Showtime has sought for years," they say. Check it out Sunday at 10 p.m.
