I was done with ER once Mark Green left. When they started really getting away from their original mission of showing life in an ER (which they did really well the first couple of seasons) and started being overly obvious about pushing political agendas, I lost interest.
Oh yeah, CSI is one of my favs, along with Without a Trace and lately, Criminal Minds (I adore Mandy Patinkin--we've seen him twice in concert. Great performer!). I also watch Dog the Bounty Hunter just because it's so darn quirky. Jimbo just shakes his head in wonder at that one.
I'm off to go write the next chap.
