The only thing I'm really (re)watching at the moment is Fringe season 2. I've just about given up on all the DC shows. They all seem to have jumped the shark now - too many characters with new ones who aren't very good. Arrow's the prime culprit. I really, really hate what they've done with Wells in The Flash. Even Supergirl has taken a nosedive and I used to be able to rely on that for a few laughs, at least.
Really must catch up on Agents of SHIELD, though - I'm about four episodes behind at the moment
