What about timing it to when you finish at the exact same time the finale ends, but keeping the binge nature intact? There have been 67 episodes to date. And the final season is only six episodes. So, minus the series finale, you'd have 72 episodes to binge before the finale. And if, hypothetically speaking, you watched one episode a day, you could start exactly 72 days before the finale, ultimately ending at the same time as everyone else. You could come up with whatever your preferred method is, of course, I'm just using that simple math as an example.
Ha, I don't know why I'm so invested in this, but the final season is going to be so massive, and so massively popular, that I'm legit concerned you'll accidentally get spoiled. That, and I can't imagine not wanting to experience at least a small portion of this show - maybe the most popular show in the modern TV era - along with everyone else. But to each his own...
