I'm under the impression it's very much in the "Crosses The Line Twice" style of Kick-Ass.
That's an unusual way to describe Kick-Ass. And yes, I'm aware of what the term means.
It's another Mark Millar adaptation. His violence is gratuitous but it's 'comic' so you have to be faithful to that. There's a scene in
Kingsman which is downright silly, with a touch of
Willy Wonka about it but probably the most contentious (and I have no idea how this will play in the US) is an entire church congregation killing each other in a rampage using chairs, bibles, crucifixes and anything they can use within the building. It's set up in such a way so that you don't 'object' but it seems to annoy more across the Atlantic than it does here.
Kingsman is actually very well..uh...executed. There's nods to Bond but also to other parts of the genre, a little bit of Alan Moore and even the recent trend of 'Nordic-noir.' Despite being more violent, it glorifies it less than
Kick-Ass and it lacks the same sort of sexual undertones.
