“but I like the Boruto kids!”
This is actually an objection I feel deserves a response. I more usually hear it in regards to Sarada, but the basic principle is the same: the new generation is so cute and great, therefore we have to allow the actions that lead to their creation.
Let me give credit where it is more than due: Kishimoto is an amazing character designer. He creates wonderfully different characters, both in their art and personalities. He makes beautifully flawed characters, characters that are rounded and practically jump off the page and into your heart within a few panels of their introduction. He even makes gimmick characters that are so much more than their gimmick–Might Guy is one of the best “gimmick” characters ever IMO.
If everything about Naruto was as bad as its ending, nobody would give a shit. It’s because the characters are so great that we want to see them having an ending worthy of them!
It shouldn’t be a surprise that the new generation Naruto characters are endearing. This is Kishimoto’s strength. But you know who could have been just as fabulous? The child of any of the following:
None of whom get to have independent existences because the plot requires them to serve Orochimaru.
Hell, Mitsuki could be Kabuto’s kid, given all the craziness that’s already occurred to Kabuto and his genetics and chakra! No further child mindrape required.
