Fun isn't the word I'd use, most of the dialogue is just the MC stating the obvious or swearing. There's pretty much nothing that ties into Resident Evil at all. None of the characters, none of the monsters, I'm not even sure if Umbrella is in the movie either. I missed the start of her stream, so maybe they are, but I wouldn't be surprised if they were just some generic organization. The monsters seem cool, I'll give it that, but that's all its got going for it.
To be honest, cool insane monsters might be enough. A lot of the live action RE paul movies were pretty bog standard when it came to that. We always got zombies and they were pretty decent but BOW's? ehhh
They liked using lickers and dogs a lot in most of the movies, but Giant T Virus monsters and Tyrants weren't given a lot of love. We had Nemesis clumsily walking around in apocalypse
and Iain Glen getting turned into something that looked like a tentacle tyrant in Extinction, but after that it was just inexplicably bringing in ganados zombies from RE5 to promote the game.
They did made Giant lickers a thing in retribution though.
Ironically the worst one in the franchise final chapter, is the only one that actually had some interesting original monster designs. ( for what little time we see them.)
I mean heck the final fight in FC is literally our hero's fighting a cyborg that looks like a completely normal human being. The Paul movies besides extinction suck at giving proper final fights against big fucking monsters.
Funny enough, the Netflix one had the coolest depictions of giant T virus spiders and alligators ive seen. They actually leaned into that shit and had fun with the concept.

I was particularly fond of how they treated lickers as actual threats that had to be avoided. They ended up shredding an entire umbrella security team in the one scene they have and the POC heroine had to be quiet and escape.

(legit liked how she was written to be intentionally terrible at fighting)
Lastly welcome to racoon city had some really fun practical and PS2 Burkin
Honestly my favorite zombies in the franchise are the ones from Welcome. The way they slowly lost their humanity and had some self awareness of it while falling apart like people dying from Nuclear radiation was unnerving.
