In Part 1, many wanted to be the best, not Naruto's second. In Boruto, that's not the case.
Boruto isn't the best so why would they want to be better than him? In Naruto characters had goals and worked towards those goals and did training to reach them. Boruto pulls things from his rear end like no man's businnes.
In Boruto apart from Sarada I don't see others with goals and doing what is necessary to achieve them. And everything revolving around Clone (Boruto) and his character doesn't help the situation either.
Competition/rivalry was embedded in Naruto’ story. This isn’t that.
Can't have a story without conflict.
