Meh. Looks more like the new Alias(total meh) than the new LOST, and really just seems like standard Sci-Fi channel stuff at best, maybe with a little more budget and less comedy. It also seems much more suited to a mini-series than a seasons-long TV show(which the directions LOST has been forced to take due to the demands of dozens of actors' personal lives is starting to convince me might be a much better medium for this sort of thing).
Also, "from J.J. Abrams" could mean he got up, called a friend and said "I had a dream about a guy's face melting on a plane or something last night, and I think there was a cow in a high-tech machine at one part... man, I don't even know. Anyway, write that down and I'll give you some more input after I see a season of the show".
