Might help a little but I still expect the game to be a flop.

Well the good reviews have convinced me to get the game. I honestly had never heard of Bayonetta before this year, and wasn't really sure if I should get this game. After seeing these great reviews though, I have to get it!

They should help but by a small percentage, maybe it will increase the sales by 10%, nothing else.

+50k at most. I hope it does more though.

It will help, but it also will need word of mouth from those who bought it. Maybe an endorsement from tons of influential Youtubers or something? I don't know.

The thing with reviews is that they really help if they are combined with lots of hype preceding them, and a nice marketing blitz. If it doesn't have all those things working for it, then they wont help a lot.

I never heard of great reviews not having a positive effect on how a game sell, but maybe it'll boost it by 50K at minimum. I am praying the great reviews will help move some consoles as well..

Does the game have Luigi's death stare?

It should be a big boost. Problem is that Nintendo needs to be creating a advertising campaign with all the 10s and perfect scores and quotes from all of the reviewers. Kinda like how Destiny did, but with actual reputable publications.

Will give it a minor boost, but mass marketing sells more than any good score.
