After I saw dozens of reviews about how badly this show was sort of ruined from s12 with cast changes, I tried some episodes from s13 and 14. Now I'm going back, as many people suggested, to binge-watch all the previous seasons where BAU characters had a perfect teamwork, strong characteristics, playing along with the scripts that are well-written. Most of all, I miss Hotch and honestly I don't understand why the series dismissed him (although I'm aware that he punched the producer or argued idk..) when he is one of the best characters in the series along with Garcia and Reid. I'm currently on my way to s4, and I will go back to s1 again once I reach s11.
