The Westworld movie was really, really really obscure. I think I saw it in one video store circa 1999, didn’t rent it.
I’m told that it was a cult classic, tho, which is why it got the attention to become a thing now.
We need general term for television series produced for premium cable / premium streaming services inclusively. The construction where you refer to the particular service (“an HBO thing”, “it’s Netflix”) doesn’t quite work when you don’t remember who makes it.
