“Vivarium” (** out of four) was an unsatisfying melodrama about a yuppie couple (Jesse Eisenberg and Imogen Poots) who look at a home inside a perfectly ideal suburban neighborhood but soon find that they cannot leave and are stuck inside the labyrinthine neighborhood of which there is no escape and literally drives them insane. Director Lorcan Finnegan and cinematographer MacGregor have an amusing visual style that holds your interest for a little while but it eventually grows monotonous as you realize that the story isn’t leading anywhere. This was all-too-obviously inspired by the works of Stanley Kubrick and David Lynch but this could have a 30-minute episode of “The Twilight Zone” instead.
