I actually liked it a lot. It gets more like castlevania a little bit... in. However if you don't like it half-way through. It gets better, but I doubt you'd end up liking it, as it doesnt' get that much more intriguing.
I like it better, than the symphony of the night clones that they've put out for a while. With the exception of Order of Ecclasia. It's also neat because it has the Shadows of The Collosus style boss battles.
the story sucks... but it's castlevania.
