Really enjoyed both. But I think I give it to GOT. I'm a Tolkien fan, I first read The Hobbit and Lord of the Rings about 35 years ago. I'd have to rate George Martin and his work up there alongside Tolkien. Just the sheer volume of his work (each book is over 800 pages) writing about a world,culture,political system,magic system etc etc that he invented in his own mind is simply amazing. Whilst the writers of Vikings had a well researched history to base their stories about. But both are fantastic shows.
The same but different I can't wait for the next Star Wars movie to be released

, its currently in production for release in 2015. Then it'll be a case of watch all the existing movies in the correct order to catch up on the storyline again.
