4 because the initial price is high but the graphics are a bit of a mess and you miss one of the most beautiful things the game has to offer, which is the environment you play in. You have such beautiful places to see while you're flying that, in my opinion, it's an important part of the experience.

Other than that, it's a perfect game. I'm not a fan of the series; I've seen 2-3 movies but that's it. The fact that the gameplay keeps me engaged means there was effort put into creating the game and they didn't exploit the name/franchise IP. Battery life is good and it doesn't strain the Switch; I understand this because compared to other games, when I play Hogwarts, the fan doesn't run at full speed.
The controls are also nice.
Decent gameplay length.
Good combat.
Story is okay.

I would definitely play it again when the Switch 2 comes out to see it in better graphics.

If you don't have anywhere else to try it besides the Switch, then yes, go ahead and get it and play it because it's a good game, you won't regret it. However, if you have other alternatives, it's better to buy it for another console because the game loses a lot in terms of performance and graphics on the Switch, everything is considerably inferior compared to, let's say, the PS5, and it's logical since the Switch is not made to run such demanding games.
