Day 28 - First TV show obsession
I honestly can't remember, but I would say Highlander.
Day 29 - Current TV show obsession
Alright, I change my vote: it's Lost, definitely Lost [/ETA]
Day 30 - Saddest character death
Richie Ryan, in Highlander. There had been times when Duncan almost killed him before, and Richie was one of the regulars: his death took me by surprise.
