Manga has ended
Never read the manga and the fans of it make me having any interest in it quite low.
Also just cause something has ended would not mean that people still cant talk about it afterall dbz still has discussions despite ending years ago
Lets talk about Boruto,
Boruto is trash and none of it's characters have any depth or backstory just look at isshiki and momoshiki as examples of this.
he only thing I hate is dragging/fillers and milking the series.
Depends on the filler, I mean like to name a example from naruto. I liked the kakashi anbu arc but not the ostrich ninja bits. Depends more on the quality of the arc for me if anything else.
I tend to dislike cash grabbed sequels like boruto and dragon ball super then the anime of anyone show but then again. Im the clear minority so my take really matters not.
Fillers help expand characters and rectify plot holes like the manga of dragon ball had trunks state 19 and 20 attack his timeline while the anime made it so it was 17 and 18 fixing the plot hole that existed in the manga. About the expanding characters bit, We get info about anko and how she has ptsd from orochimaru's abuse of her so yea the anime helps at expanding already esblished elements in the manga.
Cash grab sequels kinda just force themselves into the timeline without rhyme or reason like how dragon ball super takes place before the end of z yet makes many plot holes with it due to the many forms and such that do not exist during EOS dragon ball. Not only that but set rules are often ignored eg the sharrigan not taking immense trauma to unlock as was the case with madara,itachi,sasuke and so on
