Game of thrones is world's most popular tv serial.It is most viewed of all time.I had watched only season 1-3 but I was amazed by the suspense they leave at the end of every episode, which make an excitement to watch next episode.The story is very amazing.
I has too many characters and it's too realistic.
But I will not recommend it to below 18's as there are many 18+ scenes in the seasons.
But as far as a show its picture perfect and nothing is left from action, romance, drama .etc
