Just finished it. Seasons 1-3, the set up. 4-6, the mindf*ck. Originally watched Seasons 1-3 via Blockbuster DVD by mail service (Most people don't remember that is how Netflix started, DVD by mail), moved to California, and wasn't able to watch live. I rewatched 1-3, and finally finished it. I cannot think of anything else that would grip me the way this show has. I do like Stranger Things, but Season 3 entered jumping the shark territory. Hopefully they can course correct.
