Not great but getting better. Character design still bothers me, and Boruto being smug makes me think of pre-timeskip Sasuke which personally I don't really like. Also Konohamaru is a MAJOR let down. Dude should be a monster by now, but was thrown to the wayside for the development of the main characters. A damn shame. However, this is still the best chapter of Boruto.
I really don't see what of this ending is that bad... I understand if it isn't your cup of tea, but saying it's bad seems pretty unfair. I think bittersweet is better than a nonsensical "and they lived happily ever after" type of ending. I love it, it stays true to the story and it's set up; it's sad, but life do be sad too, and tha doesn't mean it can't be beautiful.
