Game of Thrones before and after the imposition of special effects

Importance of computer graphics in modern cinema is hard to overestimate. None worthwhile movie comes out on the screen, without first passing through the hands of masters of CGI. To assess the extent of the works of specialists in 3D-graphics, I propose to look at the footage from the series "Game of Thrones" before and after the imposition of special effects. If it were not for modern technology, all the action would look quite poorly.
