Finding where content is available outside the US isn't a super hard exercise, it's just frustrating. The answer at least half the time is "you can't".
As a Brit, it used to be a simple flow: check Netflix, almost certainly on there, watch.
Now it's usually not on there, and checking JustWatch shows that it's unavailable in the UK (without paying to buy or 'lease' the content, usually for a similar price to the streaming service's monthly rate).
You can see why torrenting is on the rise again: a Netflix subscription just doesn't cut it anymore, and Hulu isn't available in the UK without a VPN.
This is nonsense tbh.
This was never the case, and if it was it was because you had ridiculously narrow demographic tastes.

Canada and the US have 10-11% more content than UK. The disparity was much greater before most content providers left Netflix and before the advent of Netflix's original programming.
It was and still is even worse for other countries (I live in Sweden, it has 30% less content than the UK)
