A non story that makes the one of "Saving private Ryan" look like the Godfather. Non-characters ala "Dunkirk", but without actually committing to it, giving the two leads a handful of "emotional moments and lines" (some fine, some absolutely ridiculous and forced) typical of usual archetypes and basic "emotional arcs". A gimmick (a really impossibly hard gimmick) "one shot movie", that is ultra clearly not one shot and requires excessive "non scenes" where nothing happens other than people slowly walking, slowly crawling, slowly jogging. And a handful of specially great and breathtaking visual sequences that has little to nothing to do with being "a one shot movie". Those same sequences in a "normal movie" would've been incredible too, regardless.

So. A zero for the story. A zero for the characters. A zero for the score. A ten for the technical tricks. A ten for the imaginative ways of putting action and the ways there were filmed. A ten for that handful of amazing visual parts. And a zero for the absolutely ridiculous moments that are supposed to give you the chills.

I guess if you were "into the movie" from the start, and the trick one shot made you feel "there with the protagonists", then those moments would've way more impact to you and increase the enjoyment. It wasn't my case.
