> Much of the footage used in the film is borderline unwatchable without the post-processing used

That's an interesting commentary on how much technology has advanced, and how we have become so desensitized to it. Consider that when silent films first started, the movie of a train coming right at the camera scared the audience so much that they ran out of the theatre to get out of the way of the train, IIRC.

I agree on your point regarding engaging audiences. Saving Private Ryan and Dunkirk probably taught more people about WW2 than many classes or books.
