Apple's shows can be hit or miss but this has hit the sci fi sweet spot with a really great plot. Would recommend this to all sci fi lovers and although the first episode is a bit slow the show appears to slowly crank up the heat and is getting better and better. This may be a show worth waiting for all episodes to come out and binging on to appreciate the crecendo a bit better. Great acting from cast and little to be missed from a directing point of view as transitions are smooth and the plot can easily be followed. Although I have not read the book the show can be appreciated as an adaptation really well.
