I don't know where else to put this, so I thought I'd just leave this off there. Just some very broad observations about the new class of shounen anime.
I've been re-reading/watching some of the oldies lately (Naruto, One Piece, Kenshin), and something really struck me. The time the oldies devote to setting up and wrapping up their arcs makes for a much better delivery of the themes and narrative for the arc. Shounen paints with such a broad and colorful brush for its characters and themes that that time used to breathe really helps me settle into the nuances of the shows.
JJK, MHA, Demon Slayer, etc. move with such swiftness that you're never in want for an interesting episode. But often times when I get to the end of an arc that's 5-8 episodes long, I feel the themes or messages that are there struggle to stand out, and the series keeps rolling right along. I got to the end of season 4 of MHA and thought to myself "man I'm excited for where this is going, we're getting close to something good". But I thought the same thing after S3, and S2. I'm 88 episodes in, and even though the show is much quicker paced, given the same amount of episodes, I feel like I've made more headway in Naruto or YuYu. Pound for pound there are probably just as many or more great moments in MHA as there is in anything else but it feels those moments are dampened as they get swallowed up in the familiar cycle of school, test, bad guy of the week, school, and so on.
Just some random thoughts.
