I'm not sold on Dekker's John Connor, though. And while I would, of course, liked to have seen Linda Hamilton as Sarah, Heady seems to be doing a decent job. And, of course, I'm glad they ditched T3 completely and went off of T2.
At the same time, I'm concerned at how this is going to play out as a series. I think they should treat each season as an extended episodic movie, and limit each season to 13 episodes rather than 24 or so (another thing that makes me feel I'd like it more were it an HBO Sopranos-esque series).
