[I had a break from anime, so I'm not sure if I could remember most of the details I've noticed.]
I could really tell that the directors of this season stepped up and made it more daring. I really like how the screen is very expressive that they can bring the humor by themselves.
Season 1 already brought forth the god-tier humor of this anime, this season topped it off. I was expecting it to be fun, but the hilarity it displayed was really unexpected, which made it even more fun to watch.
I like it even more because it presents itself with what it is. It mixes the comedy and the serious tones very well. Ishigami's backstory was convincing enough.
The end credits was really an original in anime! I don't think I've ever seen an anime somehow break the fourth wall, referencing to the first season's opening clip.
