Yeah, Bayonetta is awesome - even the PS3 version (which is now fixed, AFAIK?) has something of an unfair reputation. The loading times (loading time for pause menu!?) were bad, but not bad enough that you should have avoided it if it was your only vector of Bayonetta worship :)
It's a shame about the WiiU exclusivity, I can't justify picking up a WiiU just to play Bayonetta 2, and I've not seen enough other titles that impress me sufficiently. ... but let's not turn this into a WiiU debate.
Anyway, it's got some great music that is unlikely to leave you for years to come! ;)
