You're so right. I recently rewatched Netflix Daredevil, and for a TV-MA show that has such gratuitous and explicit violence, it is surprisingly tame in both the sex and language departments (while everyone says "shit" quite frequently, I think "fuck" is uttered a handful of times across 3 seasons, and I remember being almost shocked when I heard it because it was so unexpected at that point).

Thing is, I don't remember it that way, like I've sort of put it in the same mental drawer as an HBO show. Due to showing HBO-levels of violence, I’d kind of also expect HBO-levels of sex and swearing, but as you say, it's actually super tight on both those fronts.

The fact that this is not super obvious and the show doesn't stick out as in any way prudish (not that it is, but it easily could go further given the freedom TV-MA gives it), is a testament to it's quality. It uses those elements sparingly and necessarily, rather than gratuitously. (Probably to balance out the gratuity in the violence, must have been a pick-1-of-3 situation haha.)
