I have some mixed feelings about Invincible, though they obviously are positive enough for me to start a full series reread. In college, I used to own a hardcover collection regrouping the first several TPBs, but I gave it away when moving to grad school. I was bothered by the violence and gore then, and now I can add to that the casual homophobia and ableism of the early 2000s and the low-level objectification and misogyny that are in most superhero comics.
