May be a bit young for it but I absolutely loved 'Love':

Some of my other less favourites but still amazing:
- Ozark, it's dark and gloomy but a solid 10/10.
- The End of the F**** World, it's good but quite dark.
- Better Call Saul, as long as you've watched breaking bad.
- Black Mirror...
- GLOW, it's super light hearted and funny.
- Stranger Things, obviously..
