I would ditch all of the parent problem plot lines and give these kids some real issues or goals. All of these "I want daddy's attention, I want daddy to be a certain way, boo hoo" issues from the likes of Boruto, Sarada, and even certain side characters such as Chouchou/Shinki, make these kids seem a lot brattier and a lot less worth caring about in comparison to Naruto's generation who faced real issues such as clan/racial discrimination, genocide, being orphaned, war, etc... Plus, the plot points of Naruto and Sasuke supposedly being these neglectful fathers are so forced.
Ditching the parent problem issues would also give other characters more room for development, and it wouldn't be so that everyone is irrelevant except for Boruto. Take Sarada for example. A lot of people, myself included, would love to see her actually be important and get development/screen time/etc...
However, the problem with Sarada and her potential for development is the fact that Kishi pretty much oneshotted all of her potential development in Gaiden. The only real issue that Sarada has ever really expressed was the whole "I want papa. Is mama really my mama" drama that we saw in Gaiden. After Gaiden resolved that issue, Sarada had no more problems and no more elements to drive a plot. Her hokage goal alone doesn't really drive a plot since the pursuit of that goal really only entails being a good shinobi until you are simply chosen for the position. In other words, you just have to do your job well enough to get recognized by the village.
That alone doesn't drive a plot however. Even the story of Naruto wasn't really about his path to becoming hokage. Naruto's story had a plot because he was related to actual sources of conflict (ie. akatsuki was after him, he wanted to get Sasuke back, etc...) Sarada is related to no such thing (she has no particular relation to kara right now, nor is she particularly of interest in the eye of the Otsutsuki clan, she doesn't have a karma seal, etc...).
Having said that, if Kishi had Sarada focus more on something like finding out about the history and fate of the Uchiha clan, or had some villagers hating on her for being Uchiha and being related to former criminal Sasuke, to kinslayer Itachi, and more distantly to Madara and Obito, then Sarada's character would have a lot more room for growth and development.
In short, this parent problem route with the new gen was not the best route to go down in my opinion.
