Do you mean Scarlet and Violet? I largely agree, but the Blueberry Academy DLC was pretty good. It is set in Unova with a lot of Gen V pokemon added and references to those games.
In general, I’d say that the SV main game is one of the worse ones, but the post-game is among the best.
Gen 5 is still the best though.
All PS3’s could play PS1 games too
