I really enjoyed the first season of the show and it's definitely something you should check whether you like mystery or not. It's just great television all around: Well written, great acting, cool soundtrack, emotional - I could go on and on! So go ahead and watch it but just stop after the first season. Seriously, just ignore the rest of the show. It's a cynical cash grab and a lazy mix of fan service and 80s nostalgia. Like most Netflix shows I had it playing in the background while cleaning the flat or doing laundry but I wish I hadn't since it almost ruined the first season for me retroactively.
