When I originally posted, I hadn't seen all of the second episode, but now that I've watched it all, I have to admit that I liked the "odd couple" element of Bennett and Sylar working together. I thought the first season was one of the best seasons of television ever, and I would just hate for it to degenerate into a big mess.
Which superpower? Well, obviously I'd like Peter's ability to acquire any other power...that would be fabulous! But so far as "single" superpowers go, I liked the muscle mimic power that enabled Monica to learn pro wrestling, double dutch, and kung fu. I could finally master those complicated step routines...
