Critics Consensus

Family drama mixes with virtual online action in the breezy and entertaining Summer Wars.

Phil Hoad

Guardian

Battling an apparently motiveless AI, it feels increasingly consequenceless, as virtual action often does. But the narrative complexity and bravura imagery still impress.

Rated: 3/5

Anton Bitel

Little White Lies

Far from resorting to easy, reactionary technophobia, Hosoda shows Japan's age-old traditions being upheld throughout different generations, with the beautifully realised digital community of OZ proving as much the solution as the problem.

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.

Elements of Madness

... proclaiming the importance of helping one’s community before helping themselves because the act of protecting the community makes one stronger whereas focusing on self makes one weaker and more vulnerable.

Where it is far from perfect, Summer Wars feels perfectly in place in Mamoru Hosoda's filmography.

I love this movie! The visuals in the real world and in the virtual world of Oz were spectacular! And the characters were all very likable! The story was simply brilliant, and the dramatic and upsetting moments were genuinely effective, must-see! I’m glad I got to see it on the big screen!

I watch this every year in the summer, as close to August 1st as I can get. This was the first time I got to see it in theaters and it was beautiful. Summer Wars should be a staple in every household, especially those with a strong matriarchal presence.
