DMC5 was bad, and Bayonetta 3 somehow managed to be worse.
It's like P* is embarrassed that they initially conceived of Bayonetta, both the character and series, as unapologetically sexy and self-aware in a fun way, so to prove that they're Totally Serious Business, they try to inject "more gravitas" into the plot but shoved all their bad-fanfic-tier information in the dossiers for the characters (the FFXIII "the game is in the Datalogs" bit), then bring in an incompetent and downright poorly designed/ugly character to take the reins for the future of the series, and proceed with the constant killing of Bayonetta and the total indifference to Jeanne.
Like they got hung up on some criticism that Bayonetta (and Jeanne by association) were both "unflappable Mary Sues" who "weren't relatable" and needed to be taken down several notches, leading to a bad writer (or multiple bad writers) devising of an Anti-Sue to be the new protag because they think an incredibly flawed and good-for-nothing protagonist is somehow better than a strong and competent one simply by virtue of being on the opposite side of the spectrum. The character has no purpose, doesn't bring value to the game or its story and could easily be removed and replaced with a post-it note, and there's a bottomless void where their charisma should be, but they're just expected to get credit for existing.
Just ignore the parts where the game itself vacillates between Bayonetta being nerfed and her being more OP than before, engaging in the exact problem it claims to solve. Bayo gets plenty of pop-off moments and outrageous moves that she didn't have in the previous games, and the enemies are designed around her skillset, assortment of weapons, and the Demon Slave mechanic, to make her look more badass than before only to walk it back a cutscene later. Anyone remember the detail about Umbra Witches going through grueling, intense training, where fledglings could die from so much as failing a Witch Walk up a wall? And the main driver in Bayonetta 2's plot was that Bayo was caught off guard for a millisecond and almost got one-shotted if not for Jeanne taking the hit? In-game feats show that she's durable (she was headbutting skyscrapers since the first game), but she still needs to be downright flawless in every facet of battle where possible in terms of speed, etc. because if she makes a mistake, she goes straight to Hell.
Wait, did we emphasize her durability and speed? Nah, she doesn't need it anymore. Bayonetta in this game can repeatedly rip her own heart out of her chest and stand around doing a long-ass incantation, like that's not dangerous to do. It's clearly not fatal since she can regenerate now. She can also fuse with her contracts. (Shouldn't Jeanne, being a prodigy just as powerful in her own right, be able to do these moves too since at least the first game? Don't think about it). But also, because the plot has to happen a certain way, none of these brand-new abilities work since Singularity will no-sell it in a minute, and multiple Bayonettas get caught off guard and slaughtered in such quick succession it's a wonder if any of them experienced or survived the events of the second game.
Even then, it's no longer necessary that Umbra Witches be highly precise in execution of attacks and dodges or well-versed in all manners of disciplines like we were told they had to be, because Viola and her Mommy-didn't-teach-me-to-properly-Witch-Time self is here and not a blood splatter on a wall somewhere. How does she know both Bayonetta and Jeanne in her world yet is so disconnected from basic Witch functions? Don't think about it.
If Platinum weren't bad at math, I'd say Viola comes across as a calculated effort on their part to get fans of her but who hated Nero to implicitly admit that it was never about how Nero was executed or the plot that he was in. Viola is exactly the tryhard, bottomlessly cringe, wannabe edgy, new replacement protagonist that Nero supposedly was in 4. Except he had two games to cook, and both are games where he shares the spotlight with another character but still performed with some level of competence (IMO he suffers from not getting his debut game to himself. Imagine playing DMC1 but you have to play as some other non-Dante dude for even a third of it).
Viola gets the distinction of being the worst parts of 5!Nero, Luka, and Bella Swan and Katniss Everdeen. She spends most of her time acting like a child, doesn't develop in the story, is responsible for multiple major character deaths due to her incompetence, then gets an undue torch-pass in the same game she appears in despite never once actually proving herself worthy of it. She doesn't have enough missions in the game to get people used to her character or want to play as her, there's nothing in her moveset worth that want, and the enemies aren't even designed for her. Her story dials up the slapstick way too much and she engages in a weirdly dated but played-straight stereotype of "dyed hair punk millenial/zoomer (who's Not Like Other Girls!) demanding respect when she does nothing and eats dirt" nonsense that I'm pretty sure no Bayonetta fan asked for, ever, not even as a joke. She also spends every other line getting triggered about nicknames and reminding everyone "My name is Viola!" like Nero went on about "deadweight" in 5 (only to abandon her name at the end anyway?), making her less deserving of the torch-pass than Nero. At least we had one other game where he wasn't being a baby over being called a name he didn't like.
So yeah, this can't be calculated, because the math is bad. Platinum seems intent on telling people "We can do all kinds of characters, you know? We're not ALL about attractive women who acknowledge that part of themselves, you know? And we can totally definitely write a story with stakes, you knoowwwww? Please take us seriously, gamers and critics, we need the money!" but they must exist in an alternate reality where they didn't develop Nier: Automata, because 2B doesn't need to look like a Tumblr reject and didn't spend her entire screentime getting talked down to by everyone including clownshoes side characters and losing every major encounter she's in. She still has that sweet katana, though.
Also, the game commits the sin of having to buy the same skill multiple times on different weapons, which I was tired of when DMC3 did it and refuse to tolerate now.
