This series is just awesome about everthing. The story, characters, music, dialogue delivery, and most effective the graphics.
Yes, it is based on the novel "Song of ice and fire" by R. R. Martin. The story between seven kingdoms for one throne takes many turns, on each corner we are seeing different surprises.
Superb war ideas, precise planning, a lot of sacrifices, bloodshed, black magic, no judgments of truth and lies, and love to the death.
Each kingdom plays a vital role in the series, and beyond human powers, we are seeing dragons, and how they grow, and how they helped kingdomes to win a great wars for a throne.
My favorite line to remember is "Love is the death of duty" and "Sometimes duty is the death of love".
This is the must-watch series.
