I've watched some great stuff on Netflix recently. As HazelGreen said, you have to search for them though, as they don't always show up on the "home page". Here are a few, old and new, that id recommend:
North and South
Daniel Deronda
First few series of Call the Midwife
The Good Wife
Pride and Prejudice
What we did on our holiday
The young Victoria
Miss Fisher's Murder Mysteries
Land Girls
Wuthering heights
Into the Wild
Still Alice
Uncle Buck
Testament of youth
Junebug
The Help
My brother's keeper (US documentary)
And many more!
I find that once you've watched something they are quite good at recommending other similar things in the same genre, so your homepage will become more relevant. I wouldn't be without it
