Warner Bros. had a bad batch of BluRays released that didn't work at all. I can tell you that. I got stuck with one for Superman: The Movie. They have a special phone number to replace them for free, but my case got screwed up. They first sent me a new f--king DVD of it! I put the bad BluRay in their envelope and sent it back after talking with them again about the mix up, I was assured they'd get it right this time, but months later I never got my replacement all cause some idiot originally reported a bad DVD so that's all that was mailed to me...
