Oz is one of the most beautiful Blu Rays ever made. But that doesn't take away from the fact. Again, give credit where due....Kudos to the studio for that. But how sad that a potentially permanent alteration was made because of an oversight. And how even sadder that the studio will take credit for the success but will not acknowledge the consumer when something goes wrong (my emails have been ignored.) And finally, how shocking that it has happened to some of the most prestigious titles in film history.
