honestly? maybe.... I think is just a "trend" bash the manga, honestly. I understand not following the manga because the art don't appeal, or due to being tired of the franchise and the characters being deformed (like me), so i think most fans that followed the manga since part 1 will move on to other and more mature things, but here and there for nostalgia will spy the new manga to see what is happening. But i'll not say "Boruto is shit, i'll never like it". Who knows?
The same author can write a great story, and make a bad sequel. Sometimes a story needs renovation and a new light because the creators get stale and just know do the same thing over and over again. Look Lost Canvas of Saint Seiya. The story was much better with another author.
I'm not necessarily saying the story will be good, and taking into account that is a shonen where probably nothing too deep will come out, the manga will obviously not be a masterpiece. But i'll keep my mind open.
