Are old movies on blu ray worth it?
Hello, I have been at a video store recently and I was surprised to find really old movies on blu ray. I even saw Casablanca in there. I thought that the only movies that could be released on blu ray were the ones from the post-HD era... or at least, the only ones that could benefit from that format. So my question is: Is there a significant difference between such an old movie on DVD and on blu ray? I already have Casablanca on DVD, so I don't know if I should buy the blu ray. Do you think it's worth it? I ask because I think old movies are the best ones and if you tell me that it's a big improvement, I will run to the store right now and buy all of them...
