Naruto
One of the Big Three, it has great side characters but never manages to do anything with them. It's more character-driven than story-driven, but somehow still fails in the character development aspect. The story itself becomes quite boring, because it's obvious Naruto will win in the end. Still, it's an enjoyable read.

Boruto: Naruto Next Generations
Ironically, this was more of a gripping read than Naruto, but the characters are even worse in this sequel with nearly zero development, aside from the two male protagonists. However, it was pretty interesting and kept me on the edge of my seat to see what would come next. The art is awful though and the main characters from Naruto are severely nerfed to the point of being useless.
