Sounds like it's The Sarah Connor Chronicles, since that's the one big fandom show-only death that happened this week that had my FList a-twitter. Although I admit I've seen surprisingly little wank about the character death, or the near-certainty that the show's been canceled. It actually seems like I've seen more quiet resignation than anything else. I think most people were just glad to get the additional season they did.

Although, this whole rant could apply equally (minus the character death) to Dollhouse, where according to fans, if you don't like you're An Idiot for Not Seeing Joss Whedon's Genius and Can't Be a True Fan.
