I was intrigued by the synopsis, but it turned out as a disappointment. Probably director and (co-)writer Justin Anderson had the sincere intention to make a moving, tension-filled drama about a waning relationship, but the chosen form was at best enigmatic; or to put it more frankly: pretentious, tedious and increasingly irritating.
The pace is extremely slow; the narrative (as far as it is discernible) is constantly interrupted by scenes that seem to be completely at odds with it, (like extensive sequences where dancers perform almost gymnastic routines, or a random naked man on a boat); the main characters (Isabel and Joe) talk in riddles and behave totally erratic; and the score is annoyingly bleak. If all this is not enough to put you off, there's also a weird and extremely cringey peeing-scene, that almost made me gasp in disbelief! The only positive thing is the photography, but that was greatly helped by the wonderful light and beautiful surroundings on this (I guess) Greek island.
The woman Kitti, who is found as an uninvited guest, drifting in the pool of the unhappy couple, walks around the premise stark naked for most of the time - sure, she has a beautiful body, but it very much impressed as deliberately provocative; her role as an erotic temptress could as easily have been achieved with a sexy bikini. Main character Joe reveals halfway into the movie a traumatic background (apparently he was once a child-fugitive from the Balkan), and then there's suddenly the suggestion of Kitti being some sort of angelic messenger who has come to persuade Joe to go home, wherever this "home" might be (maybe even "death"), - at least, that's what I made of it all.
Watching this film I only got more and more puzzled and weary and annoyed. I know, maybe my too simple brain should be blamed, stupidly missing out on tons of profound metaphors. Or could there be something seriously amiss with the way the makers have told and pictured their story? In my humble opinion it's definitely the latter.
