Guys (and girls?), a side-side-character is the only accomplishment of those villains' villainous actions in 3 seasons so far. Excuse me if I'm not convinced of both their 'evilness' and the threat they're supposed to pose towards the world.
A good villain needs to be allowed to set the tone before then the hero(es) stop his ill-doings. One of devil-Piccolo's underlings casuallly off-screen killed Kuririn and it was fucking on! In Naruto, the introduction of everything was so tough and depressing that when team 7 first met Zabuza, you felt as if the main heroes were at risk of getting killed there. And HXH is so unpredictable, you're simply left with permant nervosity, hoping that Gon will succeed.
Bnha is not like these. It has one proclaimed source of danger, but that one source fails to produce results. Think of all the greatest story, anime or otherwise - they usually start out with a victorious, accomplished villain. Which creates motivation to see him fall eventually.
That's where my criticism comes from. And I don't think bnha deserves a throw-away defense like 'then this show isn't for you'. Nah, it's just bad.
