Which poses the question: If you're after an movie that is not available on DVD for purchase, or on any known streaming platform, nor on online stores? (iTunes, Google Play Movies), with the only option is the high seas?
I don't want to cause a debate, but just asking the question what you will do in such in a situation:
Sail the high seas and get a digital copy, or choose the option to abstain? I guess it depends on the material, but let's say it is a 1980's movie. I was forced into this situation once. Cannot remember what exactly I did, though.
