has calmed down a bit.
If it's the same transfer as the HD DVD versions I can say that the Matrix movies all look ridiculously good. And the PQ gets better with the sequels. Audio is top notch (the HD DVD's were TrueHD I believe). The extras are very extensive (including engaging PiP) and the BD features Animatrix in HD. I got an Xbox Live code with the HD DVD set for Animatrix in SD and it looks like crap, way worse than the dvd. If you're a fan of the films, get this.
