Whenever it's filler, it just seems like boruto's character is meaningless.Everything he does is meaningless and for no reason.
It's like they don't have an actual "critieria" for any of the character's skills, personalities, and abilities...unless it's CANON from the manga.The manga has to set the standard. Otherwise, it's all useless, empty, and for no reason.
They're just freelancing with boruto, at this point. His skills have no basis.
Edit:You know why they don't invlove sarada much when it comes to the filler episodes, it's because they cannot find an actual PLACEMENT for her. They don't fully understand the dynamic between the characters depicted in the manga.They lack the substance for her character, sorry.
I trust only manga/canon...they're the original.UNLESS the filler is going to somehow contribute to the main plot in the manga, somehow...but it still has to be interesting.
