I remember being very afraid of going to the bathroom in the middle of the night when I was a child. Every time I went out of the room, I always felt that there was a gruesome old woman chasing me, but as soon as I entered the room, this kind of terror dissipated immediately.
The same is true in the movie, as long as you overcome your inner fear, the clown will disappear.
After watching the whole movie, I always feel that something is missing, not enough description of their respective inner fears, not enough description of their psychological changes after defeating the Joker, and the ending is a bit too happy, the Joker's true face is a big one. Spiders, and killing them with a piece of sterling silver and bare hands is too nonsense (like the earthlings defeating aliens?)
If the plot of the movie is set like this, it may be more meaningful, and the previous part focuses on rendering their inner fears (inferiority), And clowns "catch" children by hitting their inner fears. Even if they fought off the clown when they were young, the fear in their hearts was still there, and like most people, the horrors in their hearts were hidden deeper and deeper as they got older, but they could still be easily hit. They all moved forward, carefully avoiding their fears.
Years later, the Joker came back again, constantly inspiring and reminding them of their inner fears, and they once again faced their fears and worked together to defeat it. In the end, they still have fear, but they can face it head on.
Courage is not being afraid anymore, and moving forward even if you are afraid.
Back to the topic, what the movie wants to express to us is friendship, fear, and the ups and downs of growing up. Maybe different people see different angles, others see more friendship and growth.
