Personally I believe the creativity was lazy when it came to character design. The kids are literally clones of their parents. They look the same, almost dress the same, and the dame techniques. How many kids do you know today that want to be carbon copies of their parents? 

I get that the writer wanted us to understand who each character is, but good writing could've done that without assuming we're stupid. 

Now I personally dont like the new era. That's just me. I believe the show should've taken place in the same time period as Naruto without all thr technology and stuff. It just doesn't feel like Naruto. 

And boruto keep retconning the living fuck out of Naruto. Just rewriting the story that already happened. For example we watched an entire episode or two explaining Kaguya's story, her sons, the birth of Ninjutsu, etc. We she came to the Planet by herself alone. NOPE!!! Boruto threw that out the window and now she arrived with Isshiki? Where the fuck was he the entire time of the Naruto universe until now? Why didn't he try to help Kaguya? Oh they had to invent some BS excuse. 

Its so many of those things. The series cant stand on its own with destroying Naruto and its characters. 

Shino was one of the most bad ass fighters that never lost a battle that we've seen and now he's a comic relief teacher? What!?
