I am hoping the artstyle of this series keeps is more goth/grit and doesn't turn into "Anime hour"
Less grit, more goth. More camp too, as that's been a consistent staple of Castlevania. There's always been something of a campy silliness to most of the titles, which even the first Lords of Shadow had via the Chupacabras. Even Lament of Innocence and Curse of Darkness, two of the darkest entries in the series for a LONG TIME both visually and thematically (both dealing very heavily with themes of self-destructive rage and the seeking of vengeance) didn't skimp on the camp humor.
As Joss Whedon taught so well:
"Make it dark, make it grim, make it tough, but then, for the love of God, tell a joke." The older entries knew this, and we got some great moments out of it, even if it's just a hilariously anachronistic and out of place food item with a silly flavor text.
Fortunately, Warren Ellis is behind some of the best writing Iron Man and Spider Man ever got, so there's some serious potential for this.
