If I'm being frank, the Sounds and Music of this Anime make the series incredibly peaceful to watch. The score is exceptionally calming, the music is nearly constant, and even the DJ nonsense is tolerable. Overall, the audiovisual display is a cleansing experience for the soul.
This season's biggest problem is not the characterization or the animation but rather the pacing. This, however, was also a problem in the manga: some of the most significant parts of the arc flow very quickly, which often hurts what Horikoshi is trying to convey. This is unfortunate because there is some fascinating stuff in this part of the series.
There is no denying that the latter seasons of the My Hero Academia anime have been divisive, to say the least. While the anime still has decent ratings and viewership, there is a common conception among the fans that seasons four and five are where the anime started to dip in quality.
