Preacher has just started again.
That is great news, I enjoyed the previous seasons.
Rick and Morty, Brooklyn 99 and GLOW are all good for when you don’t want to concentrate massively.
Stranger things is very enjoyable, so I’d recommend that.
If you want to concentrate on something then Ozark, and Dark are good.
Dark is a German missing person thriller involving time travel, it is very good, but you need to be on the all and paying attention.
