I loved season 2, episode 1.
Glad to see that the show didn't lose any momentum coming out of last season.
I enjoyed how alive the base felt. They weren't just a tiny operation anymore. Lucy Lawless was a great (although, sadly, temporary) addition to the team. I really felt for her in the scene in the car. Probably because, damn, it's Lucy Lawless! Which I guess was the point. I was hoping it would mean she'd be a bad-ass cyborg in the series. But, not too be.
Absorbing Man was pretty awesome (and sort of hot?) and I thought they executed his powers really well. He made a great villain for the team. I also enjoyed Talbot, and the Coulson/Talbot exchange. The bit with Fitz was pretty heartbreaking. I don't know if I understand why Simmons would leave him or think it was a good idea, to be honest, though.
Skye got a full upgrade to competent agent. This gets rid of some of the complaints about her character last year, although, of course, it'll be interesting to see how the team mix shakes out with Tripp, and some of the new guys. Anyway, I was really happy with the premiere and look forward to seeing what's in store.
