Everyone knows that Game of Thrones is awesome because of the fantastic team of writers who work to adapt Martin's massive novels to the one hour episode format.  We love it because the actors are phenomenally talented and perfectly matched to their roles.  Of course we appreciate the stunning costumes and amazing weaponry.

But sometimes it's easy to forget just how important all that post-filming animation and cleanup and special effects work is to realizing the world of Westeros.  This video, which is really freakin' cool, shows a lot of before and after shots from the fourth season so that viewers can enjoy all the work that goes into a single scene on Game of Thrones.
