It's a pretty violent superhero comic book that recently got an animated series on Amazon Prime. No actual lesbians as far as season one is concerned (one or two gays though).
tl;dr It's where that "Think ____ Think" meme comes from. (even though there's one only "think" in the scene itself).
It’s really really not uber-edgy unless gore being included automatically makes it edgy. I thought it was fantastic, one of the best comic series out there. Haven’t watched the show yet myself.
It's actually really good. It tries to be more realistic take on superheroes. I did have some issues with some stuff, but overall I enjoyed the season 1 of animated adaptation. As for gay stuff. MC's friend is gay male and discount Wonder Woman is at least a lesbian in comic, but she dies in first episode so it isn't very relevant.
