I think the risk of being exposed to spoilers is something you have to accept if you want to binge watch and not keep up with the populace.

I enjoy binge watching, so I always wait for the season to complete; sometime for multiple seasons. However, I don't find the occasional spoiler detrimental to my viewing pleasure. I can only speak for myself, but I have watched many classic movies with prior knowledge of the plot; and I believe they have not significantly affected how I perceived them. Of course, it is impossible to tell if I would have enjoyed them more had I not known anything about them
