Before you view anything in 3D, please read my comments in the Wizard of Oz thread. That point made, World War Z, from Paramount, is decent looking 3D conversion.
The film received some bad press before release. A potentially troubled production. To me, it's simple.
If you like great Zombie flicks, you'll probably love this film. If you don't...
A warning also goes out to the anti-orange and teal brigade. Those who don't care of the look of two color Technicolor.
I happen to like the look of the film, but you've been warned.
Apparently shot both in digital (Arri Alexa) and analogue (Arri 435), and finished as a 2k DI, the resultant files have a highly resolved and pleasing look, with superb detail.
The audio, presented on Blu-ray in DTS-HD MA 7.1 is huge, loud, crisp, clean, pin-point, and miraculously speaking cleaning. A warning for those with smaller speakers and a powerful amp. Don't crank the volume. There are zombies that will attack your speaker system.
Once again, whether one should purchase this film comes down to genre. Love zombies, it's a must buy. Great fun, and an awesome ride.
