I just finished watching it on nbc.com. I thought it was pretty good, even though I felt that Nathan coming in to save Peter at the last second was both good and yet also a bit of a deus ex machina kindof ending.
I REALLY liked the fight scene with Sylar though, cause a majority of the heroes all came in and had at least SOME part in trying to take down Sylar, which I thought was pretty damn cool in general.
I actually am hoping that Sylar is dead for good. The guy did his role very well, cause I actually found his character to be super irritating and was actually pleased when Hiro stabbed him, fulfilling his part of the "prophecy". But I understand that if Sylar was truly dead, then who would play the villain rule.
Here's to looking forward to the second season (whenever the hell that is though)
