What is there to tell? You all know it, I even doubt anyone reads reviews for GOT. Its HBO, so its all the glory of big-budget fantasy with proper sets, costumes, CGI, all those things you normally see lacking in TV fantasy series/films.
Its pirates, what more do you want? It is a good show with good and bad guys/girls, but them being pirates it just means some people are less bad then others.
The storylines work and sure there are situations wich make you think; "really?" but again its pirates so a little weird was to be expected.
You know it is going to be the same each season but I just cant help myself. I like the gritty setting, the family drama, the veteran-deckhands, the weird customs and the bending or breaking of the greenhorns. All-in-all a great show, you know what to expect and they deliver every single episode.
