Everything is everywhere in everything.
I've been to introductory art courses where many students were able to arrive at similar understandings of various artwork as more studied art aficionados. If you were to do the same in a STEM intro course, you'd likely get special attention and it would be noteworthy.
Remember the plot fully. The dad was dying of an inoperable cancer, his son enlists a junkie to help him score heroin to ease his suffering. With the time they have left the family tries to cope with everything the dad was and wasn't.
Two incredible scenes stick out. The first time he does heroin the junkie tells him "pay attention. This will be the best experience you will ever have. You will spend the rest of your life chasing this." - I get gut checked everytime I start a new experience with a reminder to take it all in this first time.
The second is the ending of the move which I will not spoil without request.
