Glad someone else mentioned Agents of Shield. Especially season 4. Will mention few anime shows here.

How about entirity of Arcane? That show was phenomenal from beginning to end, and each 'arcs' elevated the previous episodes. Haven't experienced a show that resonated with me for a while.

Hunter X Hunter Chimera Ant: The Previous arcs like Yorknew Arc was amazing, but going through this arc felt like reading an ancient epic. Some of the elements are either make-or-break for people like the heavy reliance of narrator, the amount of chaos happening though

Gintama Shogun Assassination Arc: The entire show is slapstick comedy but has some really serious story arcs throughout the show. This being one of that I personally liked the most.
