Eh, Castlevania at least (can’t speak for the others having not seen them and having no interest in their franchises) follows the typical braindead Hollywood route of mistaking gore and swearing for maturity. I’ve been a fan of Castlevania since I was like 6 or 7 and feel like the first season was a complete waste of my time. If I wanted to watch Vampire Hunter D, I prefer to do it without a teenage redditor’s hot takes on religion.
But I’ve become especially weary of extreme violence in popular media in the past few years. I’m at a point in my life where I really don’t need that, and my only option is just to avoid that media completely.
