As a yank who has perused…and may also have been known to use a VPN to change countries to watch various things…I’ve compared the two and BritBox isn’t really the same. A fair amount of things are available sometimes, but it’s just not fully comparable.
They should sell the full service to the rest of the world like it’s presented to the locals. I’m sure there’s some Brit expats who might love to have it properly available to them.
