Deadwood. I generally hate TV drama and general series, but after watching the first episode, I bought the season on DVD and became a devotee. I mean, fuckin' hell it shits awesome.
Cybersix. Yeah it was an animation from the 90s but it dealt with some grownup themes and had amazing story and characters. Wish it got at least a second season. Sigh, I'm on a nostalgic trip right now.
Watched the first few episodes to see what all the hubub was about. I liked it. Smart and witty writing.
