I just started watching this last night and it is excellent. While it barrows elements from Sense8, The X Files, Stranger Things and The Returned, it is unique enough to stand on its own.
Initially, when I saw the promo trailer on NetFlix, I thought it was going to be like a lot of the other shows on the streaming service. However, I was pleasantly surprised.
So far, my verdict is that it is well worth the watch.
