Seems to be a trend making limited series that don't need 8-10 episodes! First episode gets you hooked but you see the signs of the long drawn-out development being framed.
Being fooled in the past from other shows, I now look for reviews that recommend the episodes to skip, that don't provide critical information. The reason for the 6 is the unnecessary episodes.
If you watch episode 1, and skip to last two 7,8... the rating goes up to a 8 for me. No critical information is missing and I like the ending, they tied up most of the plot lines.
Overall a great show, a little overly dramatized for a UK show which tends to be ground compared to US TV.
