let's be honest with ourselves, 90% of the reason to buy criterion is to geek out and place them on our shelves (ordered by the spine #) so that we can occasionally look over and smile. The other 10% is to own or be introduced to a classic deemed so by an elitist company.
And I own a lot of them...
the last thing i would do is stream one.
Suit yourself. However, I believe you have a misconception on the video quality. It certainly meets or exceeds DVD quality. Regretfully there are zero to minimum bonus features and no commentaries, which I really miss.
Regardless, I have a selection of about 400+ movies I can choose from and stream anywhere for $8 per month (I'm currently streaming Ozu's "The Only Son" in a hotel room at 480p). You could never get the speed or economy from a mail order service like Netflix and Blockbuster. Also, in case you haven't checked lately, Criterion discs are rarely available anymore.
If you just blind buy instead, well then I guess you are a moron that likes to "geek out and place them on our shelves (ordered by the spine #)..."
