I'm with you on some of that but they do serve a good purpose sometimes. All though a lot of the films they put out are B list art films, they sometimes put out great dvds of great films that would never get the treatment they receive from them. Take the films of W.C. Fields, of the large number of films he did, a lot of them comedy classics, only two dvds containing his works are available on dvd. Both of these are from Criterion. Not to mention the Janus film library, which includes the works of Akira Kurosawa among others. Although I do believe that sometimes their high prices are a bit exorbitant they have their positive side as well.
Owning a DVD player and a computer does not make you a film scholar.
Just because I don't care, doesn't mean I don't understand.
