Pokemon Legends Arceus is exactly what the Pokemon franchise needed to bring something fresh to the series. I finished the game and plan on finishing up the Pokedex, something I haven't done in many years.
However it does have it's problems, I had it crash on me once during one of the pop balloon races, and people have complained about the graphics and yes, it doesn't look as good as similar games on the Switch, like BoTW, but IMO it still looks fine.
Overall, I very much enjoyed my 40+ hours of the game and plan on playing much more of it. Highly recommended in my book!
