Orange is the New Black and House of Cards were Netflix's original leading series and both are a piece of really good tv. Really worth watching.
The current leading shows that Netflix focuses most on, such as Stranger Things or 13 Reasons Why... I'm not a fan of. They are too teenagy so I don't enjoy them at all.
If you like animation AND dark comedy, I'd recommend Bojack Horseman. Really solid show, but probably not for everyone.
