This movie is "Victoria" (2015), which he awards 5/5.
This movie runs 135 minutes in a single take, no cuts, no edits. That takes some planning. Mostly done at night, it is quite dark at times and details of faces and bodies become obscured. The filming does away with classic techniques but wins through classic story-telling. This method provides a huge amount of realism, or maybe one should see it as a different path (different techniques used) than New Wave but with a similar purpose of a different kind of audience experience.
The viewers and critics liked it a lot (7.7 on IMDB with 38,687 votes and 77 on metacritic.
I found it a bit of a slog. I was thinking at times how Germanic it was, like an overly long opera or a tome with 300 pages of footnotes. Night club scenes featuring characters dancing through blinking lights and modern music (is that today's rock?) bores me, and I fast-forwarded through the second long sequence of that. The tragic elements of the story did not, in my view, register as strongly as the story permitted or demanded. The punch was missing. Or,as critic MaryAnn Johanson expressed it:
"Mostly director Sebastian Schipper’s gimmick disappears into the background as the implausibility and the flatness of the central character — as the utter absence of any distinguishing features at all in the supporting characters — becomes the unfortunate focus."
Is this film influenced by the Cassavetes' movies? Maybe, but his movies are much better at building character.
