I guess it depends on where you hung out. I watched a lot of Two Best Friends Play and
Maximilian at the time, and they were both totally hyped, as well as most of their viewership. Because there was a big push for Bayonetta, since Bayonetta 2 was recent and a Wii U exclusive, so it was both novel and practical that she could make it into Smash.
But obviously, if you were waiting for Geno or K. Rool and got Bayonetta, there'd be disappointment, as with any time a character is announced that's no the big one you want. With so many Smash community longstanding and popular characters still not in the game, Bayonetta would be controversial in that context. Which is why I'm glad that we got Ridley, K. Rool, and Banjo altogether, so now there's only like, what, Geno left of the characters that everyone's waiting for? The only real thing that could possibly cause major controversy would be another Fire Emblem character... which happened.
My two big wants were two that I deemed way too unpopular and unlikely, so I got used to just seeing all the cool and mindblowing characters that made other people lose their minds, like Cloud and K. Rool, and just being happy for them. Then I got Dark Samus anyways, and Chibi-Robo as a Mii costume, so that worked out.
