I gave it 5 stars purely for the cinematography...

...but talk about the Emperor's New Clothes.
It was on the same level as the recent Dunkirk; looked good but absolutely style over substance. It was WW1 for the videogame generation but without the gore.
Episodic; empty landscapes; implausible behaviour and actions from all involved.
Plus if you want me to be nitpicky... church bells ringing the hour in a destroyed and inferno town; too many occasional black faces (sorry guys but even in WW2 it didn't happen like that); too many fat soldiers (Daniel Mays, anyone); too many Star Wars Stormtroopers dressed up as Germans (oh wait, perhaps it was their ancestors, errmm descendants) and the Cruel and Evil Hun Pilot! (see Flyboys). Plus a plotline that dragged out Mel Gibson's one and only great performance - in Gallipoli - into a two-hour plod. And what was Mark Strong's warning 'make sure you get witnesses' about. It had absolutely no bearing on the film whatsoever.
Unlike Saving Private Ryan or the original Dunkirk, or even Gallipoli, I won't be watching this again. Wish we'd have gone to see Jojo Rabbit instead.
