NO SPOILERS: The premise of the show definitely sounds intriguing, made me start it, and is enough to keep the first season interesting. Its good and “honest” entertainment, meaning that you should not expect anything super original or intelligent but the characters are well-defined and well-motivated and the episode plots are well-crafted and mostly make sense. Most shows don’t even reach this level. Unfortunately from the second season onward, the number of contrivances increases dramatically just so that the show can continue to happen and after being disappointed by the second season and fast forwarding through the third, I only read summaries and watched key scenes of the rest. My recommendation is to watch the first season, maybe the second, too, if you really like the scenario and then just ignore the cliffhanger at the end of a season and accept that the plot has ended there. In my opinion, you don’t miss out on anything past the first season.
