Whiplash
Whiplash hits harder and it's much more darker after a rewatch. Most people who've watched this for the first time can understandably think of the film as an artist doing whatever it takes to be great under the guidance of a teacher who is feral and strict but hey at least you're going out a perfect artist, right?
This is now the part where we are all wrong. Fletcher is a narcissistic abuser and the climax just proves that. His conversation with Andrew at the bar after getting dismissed by Schaffer where he mentions he never had a Charlie Parker and Andrew took the bait by taking his offer of playing for his new band and what did Fletcher do? He humiliated him once again and Andrew did Caravan like he's ths next great jazz musician. Sure he did amazing and it can be really satisfying, but at what cost? To just please his abuser? To get his approval? All that after Andrew cut his chances of a love life that can ease him off the pressure and maybe for his own family to just give him a bit more approval under the shadows of his other relatives doing great non-artistic stuff.
Who knows? Maybe Andrew gets to be one of the greats like he always wanted to or maybe he'll just end up like one of Fletcher's students, ending their own life due to the pressure.
And that's what made Whiplash's ending much more darker for me. Whiplash is a cautionary tale of pleasing your abuser and getting their approval under the disguise of electric jazz performances. This is really one of my favorites because I dig the score so much and Miles Teller and JK Simmons were fantastic.
