Boruto gets plenty of criticism even from me although my reasons are for recycling plots from the OG Naruto and making them worse as opposed to the characters themselves but every complaint is reserved for Boruto himself but it's not really his fault.

Boruto is of course Naruto's son, he has the same trouble making persona but while Naruto acted out in order not to feel lonely, Boruto acts out on daddy issues and the fact that the leader of a friggin country is not spending more time with him. You can already see the difference and already you can see Boruto as a spoiled brat, but that's kind of what kids do, they have different priorities especially as Boruto is growing up in peacetime as opposed to the wars Naruto battled in, his attitude reflects the world around him and he decides to follow a path that better suits him although he seems predestined to become a hybrid of Naruto and Sasuke if the teaser time skips are to be believed.
Those who hate him watched the original and Shippuden and would've been happy to end it there but Boruto wasn't made for you it was made for the new weebs and they'll either grow some taste later or think Naruto is a Fortnite character.
