Technically Brilliant, Flaws Abound

Rating: 7/10 (7 March 2020)

Visually a superb watch. That's what my 7 rating is for. Narrative and plot wise leaves much to be desired.
1. Isn't wireless telegraphy already in use in 1917?
2. Even if there's a need to send a critical written message (to save 1600 lives) by foot as if it's still ancient Mesopotamia - wouldn't one pick much more capable experienced soldiers of the hundreds available to do the job instead of two young uns lounging under a tree?
3. And for 1600 lives wouldn't you send out at least several separate small teams to Ensure at least one would get through?
4. Germans supposed to be planning it for months! Yet for some unexplained absurdity only a few mid-tier generals know about it and at the so very last minute? And these guys and their troops are supposed to have been cut off in No Mans Land and somehow have the means to suddenly discover this major German project but yet can't get a that critical message through except via two scrambling young uns? Come on!
5. Booby trapping the position you leave behind is as old as war gets ... yet two supposedly trained soldiers saunter in gaily without a care?
6. An underground explosion that could bring the structure down would mean near fatality. Even if not, ones eardrums would be a goner. Yet moments later the that same two could be gaily sharing a joke about a rat bitten ear? Huh?
7. And of course that ridiculously miraculous grazing cow and fresh pail of milk out of nowhere, the on-target crash landing plane, all that silly missed shots at close range. Wow! Gadzillions huh??!
8. Frantic frantic message to deliver frantic ... yet you sit down and listen to a lullaby with hundreds of your own troops around without raising a sigh?! Supernova huh?!
More and more huhs?! Go watch it and you'd find at least another dozen more.
It's basically a 2-hour music video suspend your belief visual feast.
