There's already many reviews for the movie itself here on Amazon, and im sure the majority of people interested in this have already seen it in one form or another. For that reason this is basically a review of the Bluray itself. As im sure a lot of people want to know if its worth trading in their dvd for.
First of all, any cool new extras? Ala's no. We have a commentary with Ang Lee and James Schamus. A conversation with Michelle Yeoh (interview). Making of featurette.... and a photo gallery. All of which were supplied on previous DVD releases. Unfortunately, they are still in SD as well.
Secondly, the sound and subtitles. Thankfully we have TrueHD 5.1 for the English dub and Mandarin track. There are a 18 subtitle options in total, including English, and English for the hearing impaired.
Finally, the picture. I wasn't blown away at first truth be told, as I skipped to one of the movies night sequences. The picture had some grain to it, although its quite mild I wonder if it has had some DNR applied to it, as on closer inspection it did appear as though skin complexions would blur a little when moving. Blacks were mostly solid although I did notice a lack of detail on them during the night scenes, especially the fast moving ones. Again, perhaps a result of applied DNR. Day scenes I found to be excellent. Very clear with plenty of detail anywhere you looked. Nice!
Overall though, the picture is good and at times very good. The print used is very clean with almost no dirt or grain to be seen. Its only the night scenes that I could find a few faults with, nothing that serious though and nothing that made me regret my purchase. I can honestly say, yes it is worth buying even if you own the DVD. It's a far better Bluray than the House of Flying Daggers release we had as well, which im sure you will all be relieved to hear.
The lack of effort put into the extras would probably push me towards giving this Bluray a 3.5 if I could, but as Amazon dont allow halves, and I think its pretty good when compared to a number of catalogue titles, I think its deserving of 4 stars.
