Starting with the good.
The story is good and its great having an open world to explore. While they claim its the first, I would say the (superior in a number of ways) sword and shield was first. That was also open world.
The bad...
The main characters designs dont feel like they belong to the series. They just feel off but similar enough that you can guess they are from pokemon, or at least some japanese game... nothing about them really says pokemon.
The NPC design is... bad. Why is there an old man in school with kids? Why are there so many buff muscle women in the world? Never seen that many even on any beach or in any gym but they are everywhere in the game.
Clothing... what were they thinking in being so restrictive with clothing options? Sword and shield gave so many lptions and this new release just took them all away. Just a couple of hats and a couple backpacks that really change anything. Shoes are not really seen or gloves or glasses. Hats, backpacks and outfit. Those are what you see.
By this point, it seems the games not that buggy. Works fine for me. Some annoying raid connection issues occasionally but sword and shield had that issue too.
I have to rate this so bad mostly because while it plays like a pokemon game, it just doesnt look or feel like one.
