I started watching season one but around half way through I stopped watching it, I wouldn't really recommend it to anyone who's into genres like actions etc, but then again it was quite good at first I just wans't interested in it.
I really enjoyed the first season. I could have done without some of the elements in the second season but overall it was still fun to watch. I will be watching the third season when it becomes available. If you enjoy simple sci-fi/horror series' then you should enjoy this one.
