@Pythagorean,
Show that died, but I watch anyways from time to time;
Dead Like Me - Fun in every way and has unique humor. Don't base everything on the somewhat wooden acting in the pilot.
Invader Zim - Jhonen Vasquez is God, Animation and jokes are great. Series got canceled because of the excessive violence. But what did the expect from the writer of; Jonny The Homicidal Manic.
Show that have not died:
Dexter - Well Jeff Lindsay's books were real bad, but the series is amazing. It follows the series killer Dexter, who only kills killers. Both seasons are great, but please get the DVD-version, many TV-channels censor it, although it does not use any excessive violence.
My Name Is Earl - So silly and stupid it's brilliant.
The IT Crowd - For IT guys only, but great with references.
Family Guy/South Park - I'm bad that way.
Anyhow TV seasons are starting next fall again.
