Must be seen for what it is.

Rating: 8/10 (9 February 2020)

This movie is mind candy. As others have pointed out, the characters are poorly-developed cutouts, and the only powerful scene is the father-son conversation. And I cannot help thinking that might be received like water in a desert. I watched it on Prime, the subtitles, I think original, and unextinguishable, are, to an Italian speaker like me, a distraction bordering on meaningless.
But I loved it. So there. I am a straight guy, so have no affinity for what some suppose to be the pornographic aspects of the film, but isolating one protagonist as a character seems to me to make it very personal, as if seen through his eyes. The sex scenes came across to me as reasonable, awkwardness in coming-of-age sex is completely realistic.
It is nicely shot, both the cinematography and soundtrack are complimentary rather than obtrusive.
If a gritty romance set in the streets of Chicago or London is what you are looking for, you will be horribly disappointed, but if you are fed up with reading Camus or McEwan, and fancy a pocket romance, it may be for you. At my age (61) I find meaningful classics less poignant than once I might, and sometimes just want to get away from it all.
