What really carries this film are the two excellent central performances from Nicole Kidman and Harris Dickinson. Without them, this film would be entirely forgettable, particularly because this film doesn't really break new ground in its genre and the plot is thin. Sophie Wilde and Antonio Banderas are also good in their supporting roles. Kidman is great in portraying a woman who wants to sink into her desires, but is constantly conflicted in doing so.
The score, soundtrack, atmosphere, the costumes Kidman wears, and cinematography all really elevate this film. The film feels very cold and aloof, which is in keeping with our protagonist. As alluded to earlier, the film's biggest issue is that the story is tenuous and not really anything new. It's surprisingly tame for what it is. It almost felt like the film was self-conscious and scared to really go there and be prurient. But perhaps that was intentional, to mirror Romy's reluctance to go there herself. While there is some nudity, it never really feels sexy. Perhaps that was the director's intent though. While sex scenes in erotic thrillers tend to be sexy, passionate, salacious, almost fantastical, the sex scenes in this film feel very organic, and even awkward at times. Between Romy and Samuel there are awkward silences, confusion as to what to do next, insecurity about intimacy. The result is that you feel like a fly on the wall. However, as a viewer, that is both positive and negative. Positive because it feels realistic, perhaps relatable. But negative because much of the film is difficult to watch. What really would have elevated this film is fleshing out Romy's past and her dark desires. A small nitpick I had with the film is regarding Dickinson's tattoos. It felt like he was a walking bad boy stereotype with all the tattoos he had.
That being said, the film is worth checking out, if only for the great acting.
