I once argued in a high school lit class that readers see symbolism in places where authors never intended. A nun once told me that if you’re looking for a sign, you can find it anywhere. As I watch “The Hummingbird Project” (2019), I see a film that’s very small (a look at nanosecond-driven, algorithmic stock trading) and very large (an audacious plan to build a thousand-mile, high-speed, fiber-optic pipeline). But there are also symbols (cue the rain) of life and death and greed and genius that are spoilers – or exist only in my mind – so I won’t mention them.
