I've played through the first Bayonetta 5 times. I'm still going to play through it just for the fact that it won't be the shitty PS3 version I've had to live with.
You deserve a gold medal for doing it 5 times on PS3 alone, holy shit.
After 5 chapters I was all like 'I'm done, I'm fucking done' then I removed the dust from my 360 and bought a 10$ copy. It didn't helped that I played the 360 version at my friend's place a couple of days before though.
Some may say that it's ''not that bad'' but I disagree, it's just fucking BAD.
One sure thing is that you're guaranteed to appreciate the Wii U port.
