I enjoyed it, and it was certainly better than I expected (not hard though - I was expecting utter crap).
I was just waiting for Robert Knepper's character to say "take my pocket, Hiro..." in the carnival, lol.
The Sylar bits were good, & Knepper's character seems interesting.
I wasn't expecting Danko to be sliced & diced in the season première.
In case anyone is wondering "I know that face...", Parkman's partner played the Cylon "Simon" in BSG, while the speedy knife guy is played by Ray Park (Darth Maul in SW1, Toad in X-Men).
Regarding Claire's new room mate, Gretchen -
