We're still enjoying Acorn for UK programming, mostly English, but also some Welsh, and some Scottish, and even some Aussie and New Zelander programming. It is interesting to watch the backgrounds as we watch the story line, to see how folks live in other nations. In some of their programming, the voice tracks are over stepped by the music which makes their accents difficut to understand at times - not often, but some program seem to do it consistently. Even if I have Voice clarification on my Sonos app playing.
We still have Amazon Prime and Netflix also. Both have extensive lists of material, but much of it is either old, or not very compelling. or both. There are several older travelogues of the British Ilses, which we have enjoyed a great deal, as we have travelled a modest amount in the UK. One on the Islands of Scotland was very interesting, Another is of a fellow who walks the trails all over Britain. It might not be to a lot of folks interest, but it is an interesting way to see precisely where British history actually occurred.
We did just finish the 6th Season ( current ) of Bosch on Amazon Prime . Both my spouse and I really enjoyed it. They are fleshing out many of the lesser characters and giving them space to grow and be of interest which is kind of cool. Just a very well done cop show with great story line and photography. Now I have to wait another year for another season.
We have Apple TV for a year for free, since I purchased a pair of AirPod Pros - and we did watch "See" Great production values, good filming, good sets, good costumes, but the basic plotline was less than plausible to me, at least, perhaps due to my previous profession. I have hoped for great material on Apple TV, but so far, really haven't found a great deal of interest to me. They do offer several cartoon shows that are well done, but not my taste. Probably much better for a younger audience with kids, maybe. Lots of programs for younger folks, and hipper folks, and I am neither these days.
I will have to go check out Criterion - it had slipped my mind, only so many hours in a day - but good quality movies never really go out of style. And Hollywood is pretty good at making sure their diction is discernable over the sound tracks, too.
