Very enjoyable indeed. Binged the lot and it was a blast.

You need to like mystery, sci-fi, subtitles (heavily used as there are migrants going to America) and having said that you need to be engaged continually to keep up.

There were a couple things that griped me, but it's more personal. I'm getting quite frustrated by the lead actor (not only in this show but others too), that has a husky voice and on top of that she is a quiet talker and whispers 90% of the time making it very hard to hear her especially the way these shows are mixed, always seems to have higher than normal background noise or music. It isn't all the women actors. Just damn annoying.

Then there are the predictables. But all in all the season engaged me, the actors held my attention.
The beetle... interesting. My overall rating for this season would be 8.5/10
