Dave Lizewski is an unnoticed high school student and comic book fan who one day decides to become a super-hero, even though he has no powers, training or meaningful reason to do so.
Someone's finger gets cut off by those bush scissor things. You don't see it up close or really at all but the guy has his finger in between the scissors then it is zoomed out and at an angle where you can't really see it but you can see the scissors closing and the guy screams. To avoid it skip 10:07 - 10:20.
There is a pretty graphic and extended scene where Kick-Ass and Big Daddy are tied to chairs and get pummelled ruthlessly on live streaming by gangsters with bare fists and a variety of other melee weaponry.
- The main character is 16 and sexualised within the first 5 mins of the movie. As well as the love interest Katie.
- also a side character saying he is "in love with" hit girl, and after being told that she looks 11, he says "i can wait, i solemnly vow to save myself for her."
At different points, people use r*t*rd" and "tr*nsv*st*te" and a character is mistaken for gay for most of the film. He and his friends say this is gross, a girl wants to be friends with him because she thinks he's gay. Several times, one character says the main character's tazer "looks gay".
SPOILER: There is clear sexual tension throughout the first half of the film between Kick-Ass and his love interest. One scene shows Kick-Ass (not in costume) applying lotion on her while topless (she's covered in the scene), but at this point, she presumes he's gay. When he comes clean with her about his Kick-Ass persona and not being gay, they become a couple and there is a brief scene where they get it on in a back alley (they are clothed and the scene is short, but it's still considerably graphic).
