The moment we give up on pushing people to challenge themselves is the moment our society declines.
Moreover democracies require an educated populace in order to survive.
I think a lot about how the movies I work give breaks to people across all workforces. Those that are trying to solve humanities diseases who need a disconnect from the workload and those that do shift work away from their families both deserve to take some time off their life and be entertained by a ferry passenger trying to escape a sinking ship or a junior exec getting hit in the nuts by a goat.
When I did a sequel of a popular movie I went deep into the hashtags on instagram and found dozens of "we watched this on our first date and now we're married, can't wait to see the next." type stories. Not a bad value for a campy zombie flick.
At the end of the day art is for entertainment. Whether or not you need the intellectually stimulating element in your art is subjective and unimportant.
Everything is everywhere in everything.
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.
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.
Art is certainly for entertainment but it's the intellectual stimulation that makes certain fiction great.
