Sure, it's more of what you'd expect out of a generic fantasy motif. But in a way, that detracts from the charm of how unique of an experience Castlevania has been. It was serious, yet dove into uniqueness and nonconformity by breaking out some awesome tunes, and delivering a sometimes subtle yet appreciable sense of humor.
Even though it wasn't generic 'epic' medieval music, it was still fitting because it was KICK ASS music. You're a badass warrior with a whip kicking ass, and making your way to Dracula. Then you kick his ass too.
Stuff generic and stereotypical material into Castlevania, and you will get a more generic and less unique experience. This is pretty much the definition of Lords of Shadow. A more generic Castlevania game.
Sure, generic sells more, but it also stifles the series' charm in the process. This is why people are having beef against Lords of Shadow, and it's more generic music.
