Actually Boruto is very popular in Japan maybe even more then Naruto was, manga not so much but Boruto anime was never kicked out of top 5 since it started in Japan and other asian countries. Go look up it's ratings.

If you don't like it, it's fine but sayin it's doing bad is just wrong, it has 0 chance of being canned it's doing rly good, if it gets canceld in Europe and America they probably wouldn't even care lol.

Maybe you do it, but you would be a minority not a lot of people and i don't even watch it as well cause i grew out of it, i watched the movie and decided meh not really for me, but that doesn't mean it's bad or not popular.

Boruto is popular and doing good, they don't really care about old Naruto viewers currently lots of kids about 15~ love that anime and never seen Naruto before, just like we did when we first saw Naruto, that's who they aim that anime for and it's working, just go google Tokyo TV rankings and you see how insanely popular Boruto is.
