Moss IS the movie. Through screen presence & sheer talent, she papers over any niggling plot holes with a bravura performance arc. Beautifully mounted & photographed film with good supporting performances, too.
The characters are minimalist caricatures, but at least the script makes some attempt at explaining the lead up & path of World War II. And there is no denying the "WOW" factor of the spectacular battle scenes involving planes & ships. Thrilling & spectacular.
