Tilda Swinton was naked a lot. Ralph Fiennes was annoying. It was a fine movie, but not compelling. Guadagnino felt like he was trying to make an Antonioni film, but this one lacked the ennui that Antonioni's most compelling films had.
Based solely on the narrative, this is not an interesting film. However, the set design and art direction (as well as the music) are a delight. Moreover, the way the film ends is striking and makes the entire story worth it.
