[quote name='probablysober']This isn't always true, sometimes the cheap studio release can be of a higher video quality then a criterion. Time Bandits comes to mind.
Oh, and some of the criterion releases have zero extra features. Alphaville for example.
Look into reviews/comparisons of criterion releases versus regular releases before paying the extra cash. Sometimes it's worth it, sometimes it's really really not worth it.[/quote]
That's right, there are a few instances of zero special features. Alphaville for example has no special features, but the Criterion version is the only official DVD copy for the United States.
Also the more well known movies might have new dvd versions that surpass the Criterion Versions (Silence of the Lambs and Robocop come to mind).
