I'm not judging the serie, I'm judging the episodes I saw, I compare the 8 first episodes of Boruto and DBS, there is no question for me, DBS is far better.No matter how many episodes it needs to start doesn’t count. U are judging boruto series based on fillers which is dumb if ask me.
The Boruto series is almost only made of filler, even if you disagree because you have your very own conception of what is canon or not.
Like you said, the main plot hasn' t started yet, who is going to enjoy watching more than 10 hours of anime (equivalent to almost 2 seasons of game of throne for exemple) without real story developpement? 2 hours was too much for me.
