For a film made and put out on disc before the launch of Blu-Ray, this is a stunning A/V feast. Perhaps a few of the long shots are not quite at reference level (e.g. some of the scrolling skyscraper shots so beloved on BD test discs) but almost everything else is! Close-ups of Will Smith awaking from his recurring nightmare are stunning in their depth and plasticity. The film features great, natural colours and superb contrasts. I can't recall any intrusive grain, and yet there isn't a hint of DNR.
But the film's strongest suit is sound. The 5.1 DTS HD Master Audio is absolute solid-gold reference standard. To paraphrase Will Smith's great line "somehow 'bombastic' just doesn't quite say it". The LFE effects in the tunnel confrontation are unbelievably visceral and intense. "I, Robot" is also a film full of superbly implemented surround sound, and always offers a perfect balance between dialogue and effects. With a decent sound set-up at home you will probably come as close here to recreating the feeling of being in a cinema as you can imagine.
The film itself is great fun, with Will Smith at maybe his most amusing in a big film role so far. For less than a tenner, this is a real bargain and will be a real credit to your HD telly or projection screen.
Highly recommended.
