A bad guy blackmails the good guys because he likes this one good girl.
My impression from the first few episodes was:
Seems "ok". Unless this has a more interesting story-arc, I won't consider this particularly good. The predictable and episodic nature of television bores the shit out of me. It makes a series only valuable only the course of multiple episodes and individual episodes become the shit I have to slog through.
My later impression, from the end of the second season:
Characters were slow and stiff until they were developed more fully. When they were, a broader story arc took hold, making this show quite a bit more interesting.
