I've been watching this show too and really enjoying it. The lead, played by Kiefer Sutherland, lost his wife on 9/11 and has raised his son, who is a mute, autistic and freaks out whenever anyone touches him, on his own. The show is based on the theory that everything in life is connected by numbers, by sequences and patterns and his son possesses an understanding of this. What seemed to be random numbers, his dad begins to realise are an attempt for his son to communicate with him and help people, as he uses sequences and patterns in numbers to be able to see timelines and therefore peoples pasts and futures.
It'll be interesting to see where they go with it because, six episodes in to the series, I'm loving it and thinking its worked very well. Whether or not it has the potential to run for a long time or not though, I'm not sure.
