I began my evening with DIE HARD WITH A VENGEANCE in Blu-ray. It's always been the weakest of the DIE HARD movies, and the Blu-ray doesn't alter that fact, but it's still a lot of fun, another guilty pleasure I always enjoy returning to.
The various DVDs (and the laserdisc) of the movie have always looked rotten: grainy, noisy, full of ugly edge enhancement.
The Blu-ray is a thing of beauty. The graininess and noise are all gone, and the edge ringing is all but nonexistent. The Blu-ray also has the highest end sound possible in its DTS-HD Master Audio lossless soundtrack. So the sound was clean, effortless, stupendous.
