I like war movies, but they have to be semi-realistic to enjoy them. In this movie it looked like everyone had just had a shower before the camera started rolling. Compare against "All Quiet on the Western Front" on Netflix, and you'll see what I mean.

Yes, the one long simulated shot was cool; for about 10 minutes, then it was just a drag, it got more uninteresting as the movie went on, and on, and...

As for the main characters, I had no sense of wanting them to survive, zero connection was developed. I just didn't care.

I would put this movie in the same category as Christopher Nolan's Dunkirk; too clean, too artsy-fartsy, unrealistic, little character development, long, and boring. Neither of these movies will I ever bother watching again.
