SMH at the people saying Bayonetta 2 didn't deserve a 10. As though any action game in this whole generation besides DMC4SE (maybe) and The Wonderful 101 can remotely compare to everything it offers.
Bayonetta 2 has a handful of relatively minor downgrades to the original's mechanics, but to make up for it you get a far, far, far more consistent set of levels, stripped of the countless little annoyances from the first game. Bayonetta 2 is streamlined for replayability, so feature-rich it almost makes the original look sparse, and packed full of bonus content and smart design touches that improve the experience.
The ideal Bayonetta game would have the original's mechanics and the sequel's exceptional variety and consistent quality and absence of unnecessarily punishing features like insta-death QTEs. As it stands, Bayonetta 2 is easily one of the top five stylish action games of all time. It could be twice as flawed as it is, with half as much content, and still deserve that 10 because its base design is so good.
