It seems an unfair match but if we're comparing visual versions there's got to be something said for depictions of gay sex (I do hope Stannis & Jon Snow find the time to do some bad Daddy role playing) in GOT that try as he might Viggo Mortensen does not accomplish in LOTR. Come to think of it I always refer to GOT as LOTR with sexy parties.
Also, one of my all time favourite scenes is when Christina Aguilera 'trades' a dragon for an army. I don't think LOTR has any scenes to match the delight I take in watching that dothraki bitch own slimy salesman guy. Also the look on her interpreter's face…priceless.
I came to say Lord of the Rings but talked myself into Game of Thrones being the better one as far as the moving pictures go. Lord of the Rings the books trump all though.
