I love mystery movies & TV shows, I think that the TV Lost was the best mystery show, once you get addicted to it the next series won't feel the same as you gained a connection between you and the show.
But, I think I found a great TV show, it's called "The Leftovers" it has 3 seasons so far and was released in 2014 with season one including 10 episodes, season 2 was aired 2015 with another 10 episodes and the third one is also with 10 episodes aired in 2017.
I am on season 2 finale so it's still too early to recommend it, but I think it will turn out to be a great show.
