No Country Released on DVD

The Best Picture winner and best film of 2007 (among many) is out on DVD. For under $20 you can be the proud owner of the DVD , or for a bit more, the Blu-ray. Is anyone really buying this Blu-ray thing?

I have seen No Country on DVD screener probably 15 times. Every time I watch it I see something new. That, to me, defines a great film. This, to me, is the Alien/Aliens paradigm. Alien is a movie that grows richer with each viewing; Aliens is a one shot deal. It is most exciting the first time through but there is much to uncover upon second viewing. Do you have any Alien/Aliens scratch tests?
