P5 game: Kamoshida is presented as a realistic abusive teacher, the implications of physical abuse being all contextualized to sports practice and you see him gossiping with other teachers and interacting with them.
P5 anime: All his interactions with other teachers are presented without sound and he just straight up beats up a girl on screen while putting on a "maniac face".
Doesn't help that the PSP remake of P2:Eternal Punishment never got a Western release so ppl who attempt to go for P1 and P2:Innocent Sin will need to emulate the (iirc) poorly dubbed PS1 version.
As for the P5 anime, I never had expectations for it. All I'm hoping is for some comedy akin to the type surrounding Yu in P4's first anime.
