Welcome back Jujutsu Kaisen. I liked the added content to emphasize the bonds of these second years, and as usual MAPPA is filling in the gaps of the manga panels with crazy imaginative action sequences.
Heard a couple new insert songs. one of the complaints of the last season is the music wasnt all that memorable. Am a fan of the new OP and ED. Good start.
New Rurouni Kenshin seems like a good starting point for new watchers who don't want to visit the '96 series. As a returning viewer, I feel like it won't offer anything other than a little nostalgia until after Kyoto. Everything I saw in episode one was done better 15 years ago.
You could basically say the same of '03 FMA compared to Brotherhood until they left Rush Valley. But I'm skeptical that this is gonna have the same effort put towards it as Brotherhood did.
