Kinda. I think itīs stupid, especially in stories that have potential for "more", but then fall short because of focussing on all the girls falling for the hero. See Danmachi recently. I really liked the artstyle and the setting, but instead of properly exploring that, it focussed on introducing new girls that would go after the hero (in before somebody claiming that itīs my fault for expecting something different, blahblah). Or take Infiniate Stratos. Really neat mecha-suits, super cool fights and great animation ... but instead of exploring that further, itīs aaaaall about all the girls having a crush on the gay hero.
Tbh even Welcome to the NHK is at fault of this. Because while the hero is a typical hikkikomori, he JUST gets lucky to have a cute girl be interested in him outta nowhere.
Itīs a cheap concept for self-deluding otaku imo.
