It's that the main characters are often boring as shit and lean on the personality trait of 'being the audience surrogate for girls' for everything.
Compare this shit to Ryuko and Satsuki in KLK. They both go through arcs, have distinct personality traits and relationships and represent interesting aspects of the story's themes.
In the West, it seems a lot of creators are so desperate to get better representation in media (which, to be fair, is needed) that they forget that stories are supposed to do more than just be shows for audiences to self-insert into for power fantasies.
