What Bothers Me Most
It's not the plot twist, or plot holes. Like how Jasmine knew where they were and how two people could climax quickly. Not the "did they really go through that whole standoff thing?" or the "true events" the film is said to be based on.
The minimal amount of nudity. Ashley and Damien were nude the entire time. With him clutching a pillow and her wearing a blanket. Sammy removes his clothes after screwing Jasmine, too. All of whom should not be so worried about their privates being visible. Sammy didn't care, so I thought it made sense. But why did the victims suddenly become so modest?
This is not about wanting to see Ashley's tits the while time or getting to see Jasmine's body, which of course I do (want to see their bodies). On the note of nudity, if they show Ashley and Jasmine, they have to show Sammy and Damien in their birthday suit. I am commenting on the camera choices and clear confusion on the director's part. They were clearly making an R rated film. If they were trying to score a PG-13 rating instead, I would understand completely. But the screenplay would require heavy rewrites to go along with the modest actors.
The writer/director's mistake was not being loyal to one rating or another. The film blurred the lines between R and PG-13. This film is guilty of Half-@$$ing both of them.
