I'm going to binge watch game of thrones every week with my friends but I'm  also going to binge watch half the season alone
Why are you going to do that?
I want to have some peace and quiet while I watch it at times.
Game of Thrones was a fantastic TV program. Wether you watch it alone or with friends it is still acceptable, so go ahead and do what you want. If you just do what your friends want then you won't be entirely happy.
I think I enjoy it so much that I don't mind watching it again.
Everyone has those shows they can watch over and over again. That's good that you've found yours!
