’Good action’?
Are you five?
And what exactly has Netflix done, apart from produce an extremely good adaptation of one of the greatest anti-war books ever written?
Maybe a WW1 movie starring The Rock, where he storms the Germans at Verdun, spouting cool catchphrases is more your level?
WTF are you expecting me to say, it was boring despite having good action, yes. Everything else was boring as fuck because the characters were cardboard cutouts of war movie characters, the message was hitting over the head every 5 seconds without being anything deep or smart and the story and pacing felt disjointed as fuck. Haven't read the book but if it's as good as they say I suspect the Hollywood idiots writing the movie cut a crapload of character development and war politics from it and made it as simple as possible.
The movie can be summarized with this: They go somewhere, great cinematography, action, soldiers die, politicians pampered assholes, war bad. Next they go somewhere else, great cinematography, action, soldiers die, politicians pampered assholes, war bad. This goes on until the movie ends.
