The ending does have a sex scene, but it's shown at a great distance

Someone tells the main character that one of the patients sewed his butt closed, this turns out to be a lie.

we see the main character's bare back in a non-sexual, but slightly sensual scene

we see a man's butt

A man and a women kiss passionately

The main character cuts her wrist and puts a wire in it, although this scene is not very graphic

Overall, not a violent movie at all, but one theme includes the main character wanting to kill the doctors, and she does so in a fairly long scene where she shoots all the hospital's staff with very bloody results, although this turns out to be a delusion

a few "F" words

none

While lighter than the rest of Park's films, this film still contains dark thematic material that may be disturbing to viewers.

The shooting scene is intense. The wrist cutting scene is might be unsettling
