Goddess, it is on ABC, it looks like it airs on Thursday nights. I have been watching it on Hulu.http://www.hulu.com/flash-forward
Benji- the autistic boy, Dylan, is not really a main character, so maybe that is why they haven't mentioned or seen him. He's in certain episodes more than others.
The premise of the show is pretty interesting, in an unexplained occurrence the entire world blacks out at the same time, and during the blackout everyone sees themselves on a particular day 6 months in the future. I've heard it is based on a sci-fi story, only in the original version the amount of time is much greater, something more like 10 or 20 years in the future.
The show itself becomes more of a puzzle/crime drama as the main character is a cop on the task force working to uncover the cause of the blackout. The acting is.. eh.. not that great and some of the story is kind of weird, but as I said it's an "all right" show.
The autistic character is first a patient of the cop's wife (she is an ER doctor), and it's revealed quickly that the boy's father has more ties into the wife's story, and possibly the story on a whole.
