It's fun to imagine what the Bayonetta cutscenes would look like if the camera treated everyone in the game the way it treats Bayonetta. If you've seen the Unskippable of the game: Imagine if we were subjected to bust shots and lingering booty shots of the undertaker. (Or whatever that Joe Pesci guy is supposed to be.)
In truth, I don't find Bayonetta all that attractive. It's just hard to get excited about a female who has the exact same physique as Jack Skellington. Call me a traditionalist, but I liked it back when women had hips and their legs didn't make them look like a strider from Half-Life 2.
Now, if we want to talk about sexy videogame ladies, I'm a fan of Tali. Although I think that's just because she's an engineer.
