I don't quite follow what you mean by reactions. Do you just mean the people on this site, or the general audience? Because it may be a little hard to gauge that until it releases here, or here it from people in Japan. Though, checking from the comments from GameXplain's videos, it looks to be an overall positive response, and a lot of people think it's like Tomodachi Life, myself included.
From what I have seen, it looks like it could be rather addicting, answering weird questions, hearing your friend's responses, and customizing your Mii. I'm looking forward to trying this out myself when it releases.
Also, seeing that they released trailers in multiple languages looks like they are taking this rather seriously.
Dance my pretties!
