I don't really see the comparisons to SOTN myself. HOD was the first IGA Metroidvania since SOTN, so obviously it's going to have a certain familiar quality to it. At the time it was really exciting because yeah, the guy was back in the game. It just didn't feel as rich and satisfying to me as COTM did, although its background are indeed lush and beautiful and those giant lanky-armed armor guys are super cool.
The dislike of the music is understandable, although I think it sounds all right, and underneath all that mess are some wonderful compositions. Not as immediately poppy as other CV soundtracks, but it's pretty complex and interesting.
If anything, AOS feels far more like SOTN than HOD does. It was the first Metroidvania to really feel like the one that spawned the sub-series. Soma controls like Alucard (except he doesn't have a down-forward slash which bugs me), he uses swords, he has a backwards dash maneuver, he doesn't float all over the place the way Juste does, and the excellent graphics and music just look and feel so much more like this was the true successor. And that's a good thing: it being like SOTN—to date the uncontested best of its sub-series—is what propelled it to being perhaps the best of the GBA trilogy (although I sometimes go back and forth between it and COTM).
HOD's similarities to SOTN are fairly superficial. Juste's portrait looking like Alucard's doesn't amount to anything within the gameplay, especially since his sprite and movements don't resemble Alucard in the slightest. He uses a whip and you can't switch it out for something else. There's two castles, OK, that's similar, but HOD surprisingly feels more lazy and retread-y. Warp rooms? Why would you want a Metroidvania without them? That's as basic a function as leveling up. Grabbing Drac's body parts, you do that in Simon's Quest as well, so what.
Between HOD and AOS ("hod aos," huh-huh), the latter is by far the one that resembles SOTN the most, and again, it's a positive rather than a detriment.
As I mentioned before, a lot of people's (I'm talking friends of mine, YouTube reviews, Kalata in his HG101 book, etc., not necessarily users on this board) problems with HOD are the floaty controls and the samey feeling of the two castles. It just doesn't hold up over time as well as AOS and COTM do, IMO.
