This is a wonderful film that I highly recommend. I have the DVD version and was excited to learn it was available in Blu-ray. I compared the two and this Blu-ray edition has a significantly better image quality, which makes it well worth the upgrade.
There has been some criticism because the audio is 2.0 instead of the 5.1 on the DVD. Yes it would have been better if they had used the 5.1 track, but the multichannel doesn't really add that much to the film. The improvement in image quality more than makes up the sonic difference.
