RHDLA is was a great series by the director of Miami Vice and Crime Story. Tom Sizemore leads a credible cast of middle aged detectives in a variety of stories. Ironically, it was Sizemore who in real life got on the wrong side of the law after beating up longtime girlfriend and ex-Hollywood Madam Heidi Fleiss during a cocaine and viagra fueled binge. So much for the real drama being on the screen.
This is a series from the director of Miami Vice and Crime Story, and the general feel is of a mix of the two, which is why it is a don't miss for fans of either series.
I don't know how much Sizemore's personal demons had an impact on the show, but they can't have helped and it ended far too soon.
It lasted only one and a half season (13 episodes), which is unfortunate. Try and catch it if you can - convoluted, action packed, and pulling relatively few punches - this show is highly recommended.
