I found this to be interesting in consideration on my research of first impressions and lasting memories.
Looking at the first and final frame of a film can be a significantly impact the way of seeing your character change or the journey. I consider the idea of bookends with complimentary images. They compliment each other by signifying a conscious thought by the director to bring you into their world and leave you thinking long after you have finished watching.
I think considering all art in this way is a good concept because making something beautiful just because is great, but it hardly commands attention and discussion. I am not talking about discussion in the idea that it calls to action some great social debate or change but merely just conversation about the piece and excites creativity in the observer to go off and make greatness in their own creative ways. This is the greatest method of learning I can find.
