Thematically I love Bayonetta, she's 100% exploitation and that's one of my filmy jams. But there's nothing to her beyond that. Her sexuality is consistent through cutscense, gameplay and QTEs without a doubt and it's great! But that means it's also really easy to understand the character.
Abby might have only seen a short amount of footage but that;s still enough to understand the character because everything she does is so consistent no matter if it's gameplay, cutscene or QTE. I just don't think the "someone who knows the game but the other person doesn't" defence holds up.
In (a ludicrous) defense of the game, nothing in Bayonetta makes any sense until the last, what, eighth? It's just batshit crazy shit for seemingly no reason that all gets backfilled at the end. The weird storytelling almost makes it easier to deal with Bayo's shit because she's kind of putting on a show, too, and just rolling with the punches. She doesn't know what the hell's going on either.
Frankly, and this is sad, but Bayonetta 2 being clearer from the beginning probably made it a weaker game. The universe really didn't get much bigger. And fuck that shitty kid and his forced walking segments, too.
