You are going to have to watch the first five episodes - which I each rate with a decent 7/10 - to be able to watch the real gem: i.e. The sixth episode. That sixth episode is just so extremely awesome, that it alone deserves a 10/10.
It is the first time that I have ever watched such an "assymmetric" show. The difference between episodes 1-5 and 6 is just huge! And after seeing episode 6, you will also appreciate more all preceding episodes.
Averaging the different scores (5 episodes of 7 stars and 1 episode of 10 stars) will give this show a score of 7.5/10. Rounding this, gives an IMDb rating of 8 stars.
But please do understand that the real gem is the last episode. And you will have to watch all the episodes before it to really understand what is happening in episode 6.
