I remember when it started there were unnecessary sex scenes - I really don't see the point of them in shows, I mean if they think it adds realism then why not show people taking a dump? ... and initially that's why I stopped watching because I just find it boring like 'filler' scenes that aren't needed.
Anyway... Months later a friend tells me the series is really good and I said I'd give it another go and boy am I glad I did! Definitely one of the best sci-fi shows I've watched in nearly 40 years. I'm so glad Amazon took this up and carried it on for more seasons.
