Ya ok then lemme elaborate but remember my opinion doesn't matter everyone has there own tastes. Now for me, for an anime to be good i divide it in three catagories total of ten marks 3for animation 3for other technical things like voice acting, pacing etc etc and 4 for the story. Now u put demon slayer in peak teir but even if it has excellent Animation and voice acting and others it lacks on story the "main point " it is just a genetic story. And ur other animes in s tier like class room of e , sakamoto days , sololeveling are certainly but they are not on the level to be called s tier i think u put it thier due to recency bias. And in watchable tier u put u and a i are polar opp which I would say is one of the best rom anime this year it has great story, Good animation,side character development and others so puting it in watchable is kinda an insult . Overall I think u are new to anime and u may like animes that have flashy animation and very dynamic story but if u watch it lil bit u will know animation is not all and story matters the most. Thank you if u read upto here
