I'm an unapologetic advocate of this series.
I hate reality television and most network tv fare so I don't usually pimp tv shows. This one, though, is phenomenal.
Watch, you won't regret it. If you get caught up on seasons 1 & 2 fast enough, you can catch AMC re-running season 3 in its entirety in July.
I haven't watched but it SOUNDS like The Sopranos in writing style and with very few plot holes. I absolutely loved Sopranos because of the flawless nature of the show. This sounds like a well made show as well.
