Getting up-to-date on 'Game of Thrones'

I've so far only finished Season One and I love it, but I know a huge chunk of spoilers for Seasons Two - Five. 

I doubt this will effect my enjoyment of the series because I already had a large amount of plot points spoiled for me for Season One and that certainly didn't hinder my viewing experience (outside of being able to see what happens to Ned miles away), but I can't wait to binge watch the remainder of the show and get to the point that most 'Game of Thrones' fans are at where they have absolutely no idea what is going to happen next.
