I don't think you're wrong about a certain reaction coming from people who react badly to any hint of counter culture. However, the series might have been a mediocre zombie survival series but its biggest issue is that it called itself "Resident Evil".

My biggest issue was just the sheer lack of polish and attention to detail. I.E: The Vegan girl wants to take some pictures of animals being tested in a BSL3 laboratory.

She asks Wesker about it and you'd think he'd just say "Yeah, we test on animals". That isn't a secret, we had a monkey shortage when covid vaccines were being developed you know.

But, the girls then manage to break into said laboratory with no resistance and when they get caught by their father... he lets them go... when they've been running around a facility that harbors possible airborne viruses and one that he knows creates violent monsters. This is, honestly, like him knowing she has rabies and not getting her tetanus. And then he doubles down on this bad decision by letting them run off to school when he should be quarantining them.

You know how Resident Evil 1 approached this? A man tries to steal the virus from the laboratory and the artificial intelligence governing the facility freaks and starts pre-emptively killing everyone.

So, you start to think... maybe there's a reason for this. Maybe the Billie Eilish fan fiction insert is like Angela Ashford who was originally given the T-Virus to cure her Paraplegia and the reason she's so violent is because Wesker has been secretly keeping it in check but it's just never expanded upon because you know they didn't read the source material and thus everything you suspect might be foreshadowing is actually just a red herring for anyone who knows the original source material.

The first movie was by no means a good movie, but it at least treated the source material well and polished its detail so that you weren't left questioning every single action the characters were taking in the sense that you're watching a b-movie horror and you're perpetually yelling at the character to not go down into the basement.
