I was "OK" with the opening episode.
THe interesting twist was that Peter "lost" all of the abilities he had gained before and now has to re-acquire them. I didn't think he had to actually "touch" them though .. I thought just being close was enough.
Sylar continues to be the character that you go back and forth between rooting for and against.
I now am officiially sick of the Hiro/Ando thread. They should be killed off.
