Sure, some aspects of the game have been changed from the original. But overall, it's still an amazing game and mostly faithful to the original. It's been exposed to loads of new people who didn't have a PS3 to play the game on, it's probably one of the best-looking games from a visual standpoint on PS5 etc.
The only gripe I have with the game is that it's, once again, stuck on a platform that probably won't be releasing its clutches from it anytime soon. Maybe a PC port is in the works, but I doubt it.
Apart from that, it's still awesome though, right?
I think some of the "cosmetic" changes hide the original artistic intent in a way that I don't like.
Like, for example, there's a statue of the old king, I believe it's behind a locked door in the first world. In the original, it depicts the old king as an anime hero, complete with improbable hair and proportions. Nobody could look at it and think "That's what the old king looked like," and indeed when you find him he doesn't look like that at all, he looks like a regular guy.
In the remake, the statue looks like an idealized but realistic depiction of a hero-king. You might look at it and think, "That must be what he looked like in his prime!" But that was not the original point—the original art made sure you knew that even at the height of his power, he was commissioning ridiculously exaggerated statues that looked nothing like him.
