Pros: cast, scenario, CGI :)
I loved the casting roles. It strucks me how they are matched. I loved the love scenes AND I don't think it's too much of sex. Well... I think that brave and obvious approach to sex in this series is one of its characteristic features so I'm fine with this. I also like how the show deals with homosexual love, which is shown beautifuly. It's probably one of the most moving threads in the whole story.
To sum up: hell yeah, I'm going to watch part 3 as soon as next weekend starts!
