Wow. That's all I can say to a season opener that is better than the whole second season combined.
Maybe it was the excitement that the show's back, but I just couldn't help but notice that they upgraded the series a couple of notches. Sylar being back really scared me, especially now that he took Claire's power. I loved the scene where he opened her head, took her power and later threw the top of her head back, it was hilarious, and it shows a different side of the series that I adore deeply, and that's the humor.
Future Peter replacing the Present Peter wasn't my cup of tea, to be honest, and I really didn't like Nathan going all religious and spiritual. But these are the only things I didn't like.
Hoping the rest of the season will be as good as this episode!
