IIRC the dialogue was "gritty" and "grimdark," judging by the snippets of script we saw, and one line involved, well, goat fucking.
I never caught that reference, but I can speak for how horrible the leaked script bits were. Knowing "animated" films today, the whole film would have been like the flashback sequences in the Dante's Inferno anime, because EDGY.
Coincidentally, the Dante's Inferno anime film was a far better Castlevania film than any of the projects we might have gotten. And love it or hate it, Van Helsing is probably the closest we'll ever come to a no-kidding Castlevania movie. Given the track record of game-to-film adaptations, I'm pleased as punch that this is the case.
