As mentioned above many times, there’s loads of good stuff, depending on your tastes, the expanse is something i watched for years and loved, same with man in the high castle and so on. Bosch is a really good detective drama based on the books, it’s a pretty simple format and works for me. The Boys again is great, same with Preacher, think the one good thing about Amazon back a few years ago was they funded projects and didn’t get involved too much, letting them do their job and not interfering.
They do a few decent new series, slow burners like Outer Range or Night Sky, again they are only one series old and working slowly, but both have stellar casts and interesting plots.
There’s just loads of stuff available on there, i’ve tried others but not really got into them, like the wilds, nine perfect strangers, etc, they will be for a lot of folk, but i just get distracted way too easily and end up binning it for something else.
