this show gives you a whole new outlook on what our future could hold. I saw 1x03 before google glass was announced and then hearing about glass got me scared as to our potential possible future going down a similar route.
Every episode brings up another topic for thought into our future and morals as a society. S1 is for sure the most memorable but each individual episode is worthy of attention. It really makes you take a deep hard look at what our society is becoming at the cost of technology, to keep advancing and the problems we could face as a society because of this thirst we have for comfort.
the only downside i found watching this series is you have to concentrate to watch it, or you will miss something, and the early parts of the episodes can seem boring at first watch, but watching them over after you have seen the whole episode you will have that "AHHH" moment.
if you are after a series to make your head-spin and bring about plenty of debate between friends and family then this is the show for you.
It is a brilliant thought provoking series and i really hope they make more!
