SPOILERS - Final Shot and Themes
While I'll admit that discussion of the pacing is valid, I am surpised that there is little/no discussion of the other elements of this picture. The parallels between the porn-filming person we never see who is controlling the young girl, with the lead trying to control the twin and virgin friend in the same choking manner, and then the lead himself becoming in the final scene the person controlled by an unknown other pointing the camera at the lead's back. His twitching and slow burn turn were mesmerizing. Who was controlling him? His peers, selling tainted drugs? The school administrators handing out meds to the long line of students every morning? Drugs and addiciton were used to control.
I was also amazed by the school therapist who routinely joked about having sex with his counselees, and also had no problem sharing what one whould think was confidential information with anyone (tells Headmaster what lead is watching online).
My wife walked into this movie midway (Netflix) and asked what was going on, and in describing who the lead was I realized he was a fairly average teenager confused about a lot of things, but that he had no one (ok, he choose no one) other than the internet to figure out life, and it was severely *beep* him up.
Was also amazed by the Headmaster whose solution to every problem was to expel someone. Combined with the lead's mother who didn't have time for his problems, this was a great set up for alienation.
Anyway, notwithstanding the pacing, I was really impressed with this film, and would like so hear what others thought of the above (and more). That final scene with the invisible controlling hand was powerful.
p.s. I never thought he actually killed the twin, as she likley died as quickly as her sister from the rat poison. Her twin did hit her head on the rail, so it is possible that both could have been saved, but asphyxiation would have been pretty easy to detect by the coroner. He did wonder whether he was a "bad person," and he was totally socially inept, but most teenagers are, in the absence of a compassionate hand to help them (I loved the "Respect yourself" banner in the rec room while his mother told him to *beep* off. that banner was REALLY helpful).
