I'll kick off the discussion by inviting you to read a 7-part series I did going through the 'small story' in
Gravity, in effect the psychological journey of Stone's character against the backdrop of the big story, i.e., surviving in outer space. I go into great detail on Stone's metamorphosis, basically sequence by sequence.
Part 1
Part 2
Part 3
Part 4
Part 5
Part 6
Part 7
In a nutshell: From a meta-psychological perspective, this story HAD to happen to Stone to compel her to deal with her grief about her daughter's death and her guilt about not having saved her daughter, irrational as that guilt might be. From that point of view, everything that happens in the plot supports Stone's metamorphosis in this regard.
The larger lesson from this is we can take a similar perspective to ALL stories, both in analyzing them and writing them. Events are not random. They occur in conjunction with the primary characters' narrative destiny, what I call the Narrative Imperative.
Thoughts?
