The visuals are great, the characters are memorable and cool, the world is atmospheric, the map is very well-designed, the gameplay is both very fun to play and fair in its challenge (you don't feel cheated even in the most difficult parts). And it also feels almost effortless in its quality. The storytelling is also top notch, it doesn't drown you in dialogue and LORE, it simply presents you with a world and lets you put the pieces together if you want to as you explore, which is key to a good metroidvania.
It didn't do anything totally unique, it just did everything everyone else did better and more tasteful.
