I wasn't expecting much from this show but I have to say that the pilot episode was a big, pleasant surprise. The concept of predicting the future isn't new but I found it pleasant to be applied in a different way than "save the world", the acting was quite good (though it takes some time to get used at the fact that the man you see on screen is not Jack Bauer) and at least this first episode had great production values showing location all over the world and making them feel quite real (and spoken in their original language). As far as the "connected stories" go I think they where well done and managed the same emotional impact in 45 movies as movies that take 2 hours to have the same effect.
I think it's too soon to call this show a success. The first episode was fantastic but I'm not sure if they will be able to maintain the same quality and engagement during the whole season. I would like this to turn into a big story rather than the "weekly connected story adventure". Still, you should at least watch this episode, even if the show doesn't manage to maintain it's quality this first episode is good enough to be recommended on its own
