Definitely fell off after S4, but I don't hate the later seasons as much as other people. Overall still one of my absolute favourite shows, although I feel like my previous 5 star rating was a bit too high (just like me most of the time).
S1-S4 probably still the best stretch of tv I have ever seen. For me S5+S6 are still very good, even if the writing goes down and a lot of the episodes get a bit boring. Hot takes: S7 still good and S8 is still alright. Terrible compared to the first 4 seasons, but nowhere as bad as a lot of people say imo. And now... my watch has ended.
