Netflix has stopped being a product I am interested in a long time ago.
When they started out, they had a lot of stuff. These days, you'll have to subscribe to 5 or 6 services to watch a lot. And every service makes their own shitty shows to attract more customers. And 99% of them suck, with the occasional succes.
Right now, Netflix is too expensive for what they offer. But clearly they think they can get away with raising proces, so I guess most people think it is worth it or simply don't care.
Just the other day, I read an article about how much cases they are able to solve because of the footage. That is a good thing in my opinion.
The police also will ask for the footage, but you don't have to give it. It's entirely up to you if you want to do so.
Even so, I prefer not to be filmed at random by people's door bells, thank you very much.
