Britbox does carry some excellent shows from the UK, but most of it seems to be archived in the 20th century and I must admit getting a chuckle from the old technology from back then with long dead actors on grainy screens. But, of course, they are largely unwatchable for me, sadly.
It is a shame when there are so many good current programs available if Britbox decided to release them - but we only seem to get a select few.
