If you are looking for a movie about two forces throwing lightning at each other, or not interested in electricity beyond plugging something into a wall outlet or keeping your phone charged, this is not the movie for you.
Being a student of Electrical Engineering, I found the story of AC vs DC current, and the lives of their inventors, rather interesting.
This movie has a very narrow audience, but to understand how this movie is set up, think Disney's "Saving Mr. Banks."
