Not the parent comment, but thought I'd answer any ways. Despite lots of looking around, I too haven't been able to find a streaming offering that comes close to competing with a well constructed Blu-Ray release.
My collection is built largely thanks to Barnes and Nobles' 50% off Criterion sales.
In addition to being a cinemaphile, i'm also an audiophile; so the lack of Dolby 5.1 audio content being streamed for the majority of movies on Netflix basically makes blue-ray/DVD my only option if I want to make use of my expensive receiver + surround speaker setup.
Do you know of any?
