The problem with home streaming is it will kill the film industry.. If you can have a steam online to watch a film legally. There will be an illegal copy within an hour.
If its a pay per view payment like a boxing match then a lot of people will be dishonest, however if the film is part of their current package, like Netflix films then people will come continue paying the subscription.
Only way I see it working is if one streaming service becomes a monopoly that we all pay for.
I have a feeling that they are going to have to find a way because I dont think cinema going is going to return to normal, like the high street its been slowing dying for a number of years and the lockdowns have just pushed them even further to the grave
