This is a strange late-period Antonioni curio, based on a Cocteau play, shot entirely on video, transferred to film, and color-corrected on acid. The drama feels a little staid, with most of the interest coming from the bizarre presentation, in which annoying digital artefacts meet psychedelic colors (the police chief literally just radiates the color blue in every scene). Sometimes it's surprisingly, even astonishingly, alluring and atmospheric, but other times it's just tacky and obnoxious.
About half way through the film, I did find myself sinking deeper into the story, due in large part to Monica Vitti, who is radiant (despite not literally radiating colors like the police chief, unfortunately). There are some familiar Antonioni obsessions, but in the end it's a minor work, and as a visual experiment, YMMV (I landed somewhere in the middle; it's interesting but it's hit or miss).
