Critic Reviews

  • Joe Morgenstern, Wall Street Journal

    The filmmakers can't keep the strands of their clumsy plot straight, but they create brilliant images and manipulate them with blithe abandon.

  • Steven Rea, Philadelphia Inquirer

    An enjoyably trippy Japanese animated feature from director Mamoru Hosoda, Summer Wars combines real-world drama (school crushes, testy relatives) with virtual-world dramatics.

  • Stephanie Merry, Washington Post

    The relationship between Kenji and Natsuki unfolds as blandly as a Debra Messing rom-com.

  • Lisa Kennedy, Denver Post

    It's a sugar rush of candy-colored images, a beautifully drawn tale of family tradition and a bracing brain tonic about the Internet's charms and vulnerabilities.

  • Kevin Thomas, Los Angeles Times

    A sophisticated yet poignant family entertainment with an appeal beyond Japanese animation buffs.

    Mamoru Hosoda's <i>Summer Wars</i> is a fine specimen of Japanese animation.<p>At first glance, <i>Summer Wars</i> seems like a comedic summer adventure in a rural setting; however, there is a pretty high degree of technology involved in the story.… More
