The films of Basque director Julio Medem derive much of their power from their constant proximity to the melodramatic, the grandiose, and even, at times, the ridiculous. As with Leos Carax or Harmony Korine, the dead-serious notion of cinema as a kind of visual alchemy pervades everything Medem does, which means that when he fails — as he does often, and with naked abandon — he provokes unintentional titters. When Medem succeeds, though, his films feel like a head rush.
