You know how, in time-travel movies, characters don’t want to change anything or else the future will get completely screwed up and bad in some unpredictable way?
I think that storyline paints a rather dismal view of our actions in the present. Because what it tells us is that our actions (for better or worse) will change the future in some completely unpredictable way — as if the universe is completely inscrutable, and the future doesn’t turn out for the better even if we think we’re doing something good. I had no idea Back to the Future was so existentialist.
