If we're going to complain about continuity then we have to note that Konami fucked things up with the whole history of the series, and matching it to Bram Stoker's book, and that doesn't even address how their depiction of Dracula, especially before his own birth, fucks up the actual timeline as well. So...
To be fair that was IGA's mistake and not Konami's. IGA made LoI that gave us a very different version of Dracula, which threw a rather huge wrench into the continuity of the series. One wrench out of several in fact but the biggest one by far. Dongled explained Konami's original history of Castlevania in his video CASTLEVANIA DECLASSIFIED. And to me at least it worked well enough and went along with what I felt about Castlevania as a kid.
What's going on with this NetFLIX series is the same thing that's been going on with a lot of other shows and movies the past ten years or so; pandering to a very specific demograph of people who don't even make up the majority but like to think they are. And who expect us to like what they serve for dinner. And of course if we don't like it we fall under numerous accusations (omitted). But the sad truth is, whatever they touch they either ruin or destroy. Maria isn't someone who's gonna mistreat nor misogynise Richter as she idolizes him. She sees him as her most beloved older brother and thus helps him rescue her beloved sister and the others. Tera had no powers and her role in Rondo was very clear; a Nun of the local church. She doesn't need powers to help Richter as she helps in her own established way (through a prayer and goodluck charm). And as for Anette herself; it's blackwashing an already established character and giving her powers too. That pretty much destroys any chance of telling the future Rondo story as we know it due to the drastic changes of these well-established characters. Then of course we have this;
Every LGBTQ+ character in the Netflix Castlevania universe
Alucard (bisexual, OG series)
Striga (lesbian, OG series)
Morana (lesbian, OG series)
Taka (gay or bisexual man, OG series)
Olrox (gay man, Nocturne)
Edouard (gay or bisexual man, Nocturne)
Mizrak (gay or bisexual man, Nocturne)
None of this is even remotely consequential to CV or the CV story. It's just forced (heavy-handed) and serves no real purpose except to pander to the aforementioned "specific demograph". If said story isn't about the above it shouldn't even be a footnote.
