the good? alot of variety. the world map is huge. combat is fluid & responsive. monsters are well rendered & the travel book is well illustrated & detailed. the "castle" section being my favorite.
now the not so good.
the story is a bit convoluted, & imo has no relation to any previous castlevania storylines, even though some have tried to tie it into others. it merely borrows names & other themes from previous CV games.
besides the obvious lacking fixed camera issues, the biggest turn off, for me, are the challenges.
I recommend you skip each on your initial playthrough, then go back (after you complete the game) & are better suited to deal with some of the very specific tasks these challenges require.
in other words, its going to be a pain to platinum it otherwise.
there are the GoW references. I would also agree with the dantes inferno reference, mainly because of the similar camera restrictions.
I do think its more epic then these games combined though, because of the super huge boss monsters & my love of the lore & universe of the subject material; even if its not entirely related to the originals.
