This movie is particular (note: unrated version, DTS selected ), one of its kind even if it uses classic elements of sci-fi big brothers, from ALIEN to ALIENS to MAD MAX etc. Technically, this dvd is fabulous: the image is extraordinary ( very stylised of course ) with incredible blues, oranges, whites etc, maximum film-like definition, absolutely no EE, superb contrast and depth. The DTS, sound oh my God!! the dynamic is out of this world, the bass are ultra deep and super tight, the violence of the soundtrack (horns and 15" help dramatically to give you that right-in-the-stomach violent punch and dialogue liveliness) is fabulous (note: the dts has a clear edge here, though a different mix is likely). The sound recording is top notch. It's systeme challenging at reference level. Buyer's beware.... It carries an undoubtful apocalyptic "we won't make it" tone and thus can be classified in the category of ALIEN 3/4, MAD MAX, SCREAMERS. Universal surely did not mess up that dvd!!! I've watched it several times, each time the impact gets bigger. Go figure.... it's the SAVING PRIVATE RYAN, sound speaking, of SCI FI action movies. That could sum it up pretty well I'd say and of course, VIN DIESEL rules! (note: he played in both...... ) system used: JBL cinema speakers and Denon A10, power amp 2x275watts, calibrated lcd projector RGB signal, 120' screen. A CRT would be ideal for the numerous night scenes where 1000:1 contrast ratio and real deep blacks are compulsory.
