I have seen the film before, and I indeed did watch it last night. The film is, and has always been, about the Ethan Hawke character, Todd. Todd is a legacy at the school; he is shy, has a lot to live up to, lacks confidence and can hardly articulate his thoughts, or his feelings. Every scene with him suggests that he does what others think he should. Note that Todd is the first to gather the courage to speak when Keating leaves the room. He is the first to defy the headmaster, and his is the last image we see in the film. Neal wasn’t strong enough to defy his father and, because he felt, trapped, ended his life. Every character surmounted to some degree—large or small—the trap they were in. The film is essentially about Todd and his growth.
