Torchwood is apparently a spin off of Dr Who, though we do not watch Dr Who. (Sacrilege, I know.) I love Torchwood because it reminds me of the early seasons of the X Files without actually being anything like X Files. Or maybe because it’s like NCIS, but instead of investigating the deaths of military men, they investigate aliens.
Even though it has an ensemble cast, Torchwood seems to focus on Gwen in the first season. She is the new person to the team, so the just like in a novel, the audience is learning about the organization through her.
