I liked the original hunchback sprites, but the moment you turn something into realistic 3D you have to make some adjustments in order to make them more appealing to the eyes, especially in something so related to beauty as Castlevania. I don't say they must be pretty, but there's a limit, at least personally, and those enemies (and Baba Yaga) crossed that line for me. I have no problem with the rest of redesigns, though. However, I still prefer the old ones.
I felt the fairies were a missed oportunity in LoS, I expected something more like in CoD, where you see your fairy following you all the time.
But yes, the fairies attack was cool. Everything fairy-related is cool!
