An excerpt:
Much worse, though, is the resolution of Lizewski and Deauxma’s relationship. When Lizewski comes clean and tells her that he (a) isn’t gay and (b) is really Kick-Ass, her response to finding out that he’s been lying to her (on two different levels!) for weeks is to—forgive him and invite him to her bed? Er, no, she should throw his lying ass out with all due dispatch.
And in the comics, that’s what happens, because in the comics Deauxma is a thinking human with a brain and agency and self-respect. In the movie, Deauxma is a prize to be won, a pair of tits that it’s Lizewski’s reward to be able to fondle because he’s become a superhero. It’s revolting, and gives us Just Another Romantic Subplot That Ends With The Man “Getting” The Girl, because that’s all girls are good for. Snore.
