It may not be the strongest Pixar outing, but Disney/Pixar's third Cars movie offers a fantastic home theatre experience.
Indeed, the folks at Pixar are really on the top of their game here, and Disney's 4K Ultra HD disc release is truly reference quality - so much so that I'll be using it as one of my test discs going forward. It isn't just the 4K picture, it's how the 4K picture takes advantage of the Pixar folks' hard work creating the "virtual world" of Lightning McQueen, Radiator Springs, and the "pseudo-Nascar" spectacle. It's remarkable.
