maybe is better if they will apply different prices based on the country where they operate, based on fact that even 1$ can be a lot in certain countries
This is certain. For different countries there should be different prices. Since a person will prefer a pirated film than pay a large price for it.
That's not a good idea in general, and I think this is a business, this isn't a non profit organization who just want to eradicate piracy.
Why not a good idea? How would you imagine they go on totally different markets with equal price? The product will fail no matter how good it is if people won't be able to afford it. Even McDonald's adjusts prices in different countries.
