One of the most unique and engaging movies I've seen in years, Under the Skin is not for everyone. The film is deliberately paced and slowly reveals its simple, but utterly engrossing plot until the last moment. Scarlet Johansson gives an excellent performance. She is the only real actor/actress in the entire movie and carries it on her shoulders. There's sparse dialogue here and there throughout and its incredibly interesting to watch the interactions between characters and Scarlet. It gives the film a sense of verisimilitude that would otherwise be lacking in an unrealistic science fiction story. There's not much else to say without giving vital information away, but if you like thoughtful and potent science fictions films that are genuinely creepy and don't mind a little bit of a slog, this is absolutely worth watching. It kept me thinking long after the credits stopped rolling.
