Very surprising storyline. I love how it kept me wondering what was going on in season 1. The main character, Nadia, leads a life so unlike my own, that it seems bizarre most of the time (which only adds to the atmosphere of the series), yet I was able to identify with her and her line of thought. Her counterpart, Alan, is the exact opposite of Nadia and the two of them for together perfectly. I was really impressed by the script, the characters, the acting and the special effects (especially in season 2).

When season 2 came out, I was sceptic, but it's even better than the first. Needed a few episodes to get used to the changed theme, though. It's also a treat to see the historical scenes with all the details (architecture, clothing, attitudes, music, technology appropriate for the given time).

All on all, a recommendable and memorable series.
