Spoiler Alert. Don’t watch it if you don’t want to know how the show ends.
I thought the first two seasons were great, after that I got quite lost myself as the story got more and more convoluted! In the end I decided to just find out how it ends. Curiosity killed the cat.
I do like the spiritual element of the show and how it touches on the relationships and bonds that can form even with some people who start off as complete strangers. I also like and somehow believe in the idea of time being non linear and I think they may be more than 5 dimensions. I think there are a lot of things that Science cannot explain right now.
