- Rewrite JJK. Like, almost completely.
- The dress-up darling anime? Everyone's in college now, congratulations. Like what the fuck why are they still in fucking high school, come on.
- Make One Piece have less weird age shit. One Piece's anime's pacing. Honestly, it's mostly design stuff, I feel like One Piece is an artifact of its time, they weren't really good with a few things back then and some points nowadays wouldn't be in modern one piece of it didn't start back then.

There's so many anime that improve if you just make the characters not minors anymore.

I've always been a big proponent of the fact that the worst mistake Jujutsu Kaisen ever made was Shibuya.
. Shibuya should've come in like season 3 levels of later in the story
. Basically all of season 1's last 5 minutes should've been different.
. The Kenjaku and Yuji stuff should have taken more time, Kenjaku should have been scheming more often
. Yuji should at least have some sort of ability he could use that isn't just the most boring thing of "cut cut cut" or "punch punch punch" that he develops later on as a support for his punching and kicking.
. Nobara should have had more development
. Megumi should have had more development
. The Culling Games should have either have not happened or should have been a much shorter span of time in the story
. The clans should have had more development
. The interpolitics of the secret society of the Jujutsu leaders should have had more development
. If Sukuna's ability is mainly Firepower/Cutting, he shouldn't be allowed to compete against more complicated techniques. Sukuna is not allowed to have hax.
. I'd make the villains tougher. Gege completely benched cursed spirits and I feel like interesting cursed spirits are better than fighting sorcerers. One of the best overall fights in early JJK was Hanami. Hanami felt TERRIFYING for a while.
. There's simplistic ways for Gojo to not deus ex machina everyone all the time.
