I binge watched this last night having avoided all spoilers but going in with way too high expectations after only reading praise and having it recommended by a friend. I guess the thing for me is that I just have a hard time to relate to it as I have no kids and when I was that age, things were just completely different with no social media and such. The 1-take filming techique indeed immediately was noticeable and from what I've heard they started making the series with that first in mind and coming up with a story afterward.
I fully understand though that many people really like it while it's not something for me I guess. If I started watching knowing there were 8+ episodes, I would not have gotten further than 1 episode.
