Technically, the movie was strong. But that's about it.

Watching the movie felt like as if everyone involved with the movie knew very well that since the topic is something that touches an entire generation of people around the world and the sheer scale and significance of the event the movie allegedly portrays, people will and should just slurp it up. Who cares about the story and how it unfolds? Why work on it when we'll just keep showing the horrors of war using nice VFX? People are BOUND to say it's good or they'll be called insensitive.

Zero efforts were made in storytelling. It was not a movie and neither was it a documentary. No story to call it the former and not enough facts to call it the latter. It was just a cheap effort slapped up together to have a sure shot way of earning profits.

And why shouldn't they? Look at the raving reviews calling it a masterpiece. They do it because it works.
