I saw it with a fairly rowdy crowd ("woo! more cheerleaders! lesbo sex!"), so I missed the lines whenever anything remotely dramatic happened, but it seemed to live up to the first season, which is a great relief.
Hiro's path seems fairly clear(save the village, get the girl), but Heroes tends to go left when you expect it to go right, so hopefully it won't be so simple.
Sad to hear that Matt got divorced in the end, but I like the two men and a baby thing with Molly and Mohinder. It's sort of cute, and adds a bit of stability to the show since Peter's lost his memory, Nathan doesn't seem to be senator anymore and Claire's moved out of Texas. Oh and I don't like her boyfriend to be. He's creepy and she could do better.
But I'm most interested in how Kaito will survive and who it was that pushed him off the roof. He can't really be dead!
