I think why people didn't complain about chapter 700 or the hokage one shot because chap 700 was released with 699 and as for the hokage one shot, it's because it was released in a time close to the boruto movie and kishi's interview where he says that he wanted to make a movie where sasuke is a main. Besides many people had other complaints about the ep, not just characters' appearances but it was overall an enjoyable episode.
Okay I’m going to reply once and for all because I don’t enjoy fandom drama. My blog is usually drama free and mostly graphics related. Also I hate repeating myself and wasting time over explaining my point of view to people that aren’t usually willing to listen (such as antis)
