I found this to be an interesting, fresh show and looking forward to the second episode. Can't see why the previous reviewer gave it a 1-star rating. It's a lot better that a lot of the crap that's on television these days.
The concept of the show is quite original with the images of an impending disaster about to happen, the central focus of the show. The clock ticking down to the event helps to keep the tension and suspence up. And showing the images for the next week at the end does heighten the anticipation. The lead characters are appealing and a diverse; each having their own reservations about the upcoming even.
This is a great sci-fi show that has a lot of promise.
