Warner is very love hate with many people regarding bd, but if your a fan of older classic films you generally are a fan of warner.
They are the ONLY major studio consistently releasing any sort of quantity of older films on blu-ray, and they are the studio that is releasing the most blu-ray titles total so I don't think it's a stretch at all to think of them as the best studio.
Of course Criterion is excellent, and I love their releases, but if I had to name the studio that has contributed the most to bd overall it would have to be Warner.
and they will continue to lap the field because they are the studio most dedicated to releasing their amazing catalog on bd.
sure they have had some poor releases, but they have had some amazing releases also.
I mean good god they have put out great bds of "Gone With The Wind", "The Wizard of Oz", "Dr. Zhivago", Bonnie and Clyde", "How the West Was Won", "Gigi", "An American in Paris", "Bullitt", "North By Northwest" and many others, and are releasing "The Maltese Falcon" and "Treasure of the Sierra Madre" this Fall.
next year they are releasing "Ben Hur" and "Citizen Kane"
no other major studio comes anywhere close to touching that sort of quality as far as older releases.
I mean it's not even a contest.
Paramount has issued a grand total of TWO films from before 1970 on blu-ray I believe.
Universal has released hardly anything from before 1970 besides a wretched bd of "Spartacus".
Sony has released a few Harryhausen films, and hasn't issued ONE film that has a dvd release under the "Columbia Classics" banner, while completely ignoring all the amazing films from the 30's, 40's, and 50's that they have the rights to.
(they are FINALLY releasing "Bridge on the River Kwai" this Fall)
that's pretty pathetic if you ask me.
Warner is certainly the major studio doing the most as far as actual film preservation in concerned; as regards actually preserving the history of American cinema on this fantastic new format, while Paramount, Universal, and Sony are basically doing nothing.
