One of the best Heroes episodes ever, in my book.
I was on the edge of my seat the whole time and even afterwards when I kept saying to myself how good this premiere was. We got Future Peter, Future Ando, Future Hiro and Future Claire. We got new abilities and abilities we've seen before, only in a different way. We saw characters return, including Linderman, whose first line in the episode made me grin.
It had a lot of nods to the first season and I loved them. Heroes made a great return with this episode, tying up several storylines such as what Sylar does with the brains and some of the small things seen at the end of season two.
