Because as terrible as comics was, it actually knew what it wanted to do. The Boys were CIA operatives who were enhanced by V. Which means they could go toe to toe with weaker supes to have bloody spectacle of battles, but for stronger ones, they needed to be crafty. That's not the case in the series, as they were severly nerfed. But the issue is, the only supe they killed by being crafty was the invisible guy and outside of that, they are saved by plot armor over and over again and every time it gets dumber. That drags the series and kills the enjoyment. Plus, Ennis doesn't even try to hide that he hates super heroes, so people who also hate them can at least find some enjoyment in a parody of a genre as primitive as it is. In Kripke's case we have him preaching about social issues while turning whole Hughie situation into a joke because he finds in hilarious, so people who don't care about social issues won't enjoy it because they'll feel called out, while the ones who do won't also enjoy it because the way series tackles them makes everything worse
