Everyone has their expectations sky high. It's ridiculous. I mean i dunno about the story on SWSH, but who cares? it's a pokemon game, there's a bad guy, a rival, a professor, a pokemon league to beat, new pokemons every game, and some gimmick to make the game feel slightly fresh despite the fact that it's literally the same game we've been playing for the past 25 years.
If anything, SWSH has incredibly gorgeous graphics. Every attack has lovely and very polished particles, explosions, lights and effects going on. The enviroments could be a bit better, but compared to previous generations, again, huge improvement.
If you hate pokemon so much go play.. i dunno, monster hunter or whatever is up to your standards, because pokemon is this, the same mechanics + a gimmick + graphics that are always a couple years behind.
