For many, I believe it is more about the grossly exaggerated impact that this title, along with several others, was said would have on the Wii U's overall sales situation. A lot of faith was put in Bayonetta 2 to offer something Wii U gamers and potential future Wii U gamers, could not get by other titles on the platform and that the added diversity would help the momentum a great deal along with other games.
I'm all for a diverse catalog and believe it is among the primary concerns any platform should have but this was always a niche title, a niche title with wildly unrealistic expectations attached to it.
That's the case for me anyway, I've gotten a huge amount of grief for suggesting all along that Bayo 2 would have more or less zero effect on the Wii U's overall standings on the market and the hardware increases at release weeks and the sales of the title itself would suggest that this was the case.
It is simple to label everyone as "haters" if they bring up the low sales of Bayo 2, but one has to look beyond and also count the relatively large group of users who were touting this as a huge deal, there were several threads over a very short period of time about gamers "begging" Platinum to bring the games to other platforms and there was clearly a lot of interest in making Bayo 2 into a much bigger deal than it ever was.
For me personally; it falls into a genre I've never liked, I neved enjoyed DMC, God of War and other, similar games either so I honestly don't care. What I do care about is how when these unrealistic expectations were not met in the slightest; a considerable amount of people start collectively complaining about those who talk of the low sales and lack of impact and call them "haters", making it some sort of "rage out of jealousy" phenomenon, when this is clearly not so, especially in my own case. The OP and many other posts in here are no different.
Let's summarize:
1: Bayonetta 1 was a blip on the radar of the PS3 and 360 and yet Bayonetta 2 was touted as the second coming by some, and was always featured on lists that proved that 2014 was certainly the "year of the Wii U" (like 2013 before it and now 2015 ahead of time).
2: Bayonetta 2 did not live up to this forum hype and didn't really do much of anything except spark a post-release debate on whether or not it was ever important (hint; it never was).
3: There are morons who use it to rub it in Wii U owners' faces and are being pricks about it.
4: There are other morons who clump every critic together with above mentioned morons and whine on the internet about it.
5: I hope the whole thing goes away very soon.
