The right person can help you overcome your self-destructiveness. That's pretty much the moral of this oddly endearing love story/crime story.
The principal character--very strongly and naturally played by a not-at-all-inhibited Asia Argento (ie, lots of nudity). I was very impressed by the other main character, Jared Harris, an actor I had only seen previously as Andy Warhol (I Shot Andy Warhol). He's terrific. His voice is fabulous (something in common with dad, the late great Richard H.) He's a good guy, the clean-cut teacher who cares about his students, law-abiding, gentle, jazz-loving. She's the thief with a soft heart, looking for a reason to leave that life, looking for "family" (her childhood was not chipper). She's got an ersatz family (a dysfunctional one) with Rupert Everett (as a charming, drug-addled thief) and Jonathan Rhys-Meyers (as a pretty-boy, screwed up emotionally thief). They care about each other, but are also violent and volatile with each other.
The teacher gets pizzazz in his life from Beatrice (B Monkey); B. gets stability from him. But the dark elements of her character and her dangerous associates intrude into their lovey-dovey life, and they have to make tough decisions about how to continue together. It's very moving when Harris' character asks Beatrice, "If if was just you and me, and nothing else, would that be enough?" Ultimately, isn't that what true love may come down to? Is being with that person, like Adam and Eve, just the two of you, enough? Can you give up the thrills of a dangerous life and settle down and be happy?
The ending, violent and an ultimate test of loyalty and love, is explosive and appropriate given what came before. It's a satisfying, if gruesome conclusion to an askew love story.
I've never seen Miss Argento before, and I agree with the other reviewers that she is genuinely charismatic.
