I'm watching it right now on my Roku via Netflix. It's better that "Flyboys" imo. It's not the best movie in terms of story and narrative structure, but it looks good. I particularly like the mix of uniforms and civilian clothing that they wear, like in "Das Boot." "Flyboys" was a popcorn movie.
"The Blue Max" and "Dawn Patrol" are my favorite WWI aviation movies.
Anyway, the overriding theme is - run from a battle that you cannot win.
