Off the top of my head, here are some of the best shows on Netflix that aren't obvious like the Breaking Bads of the world.
The Last Kingdom: GOT without magic/dragons. Great show, 2 seasons so far.
Happy Valley: BBC 6 episode season, I think 2 seasons in total. Fantastic murder mystery cop drama show.
Broadchurch: Basically identical praise to Happy Valley
The Peep Show: Maybe the funniest show on Netflix, another BBC inport.
The IT Crowd: If Peep show isn't funniest on Netflix, then this one might be. Another hilarious BBC entry.
Mindhunter: A bit of a slow burn, but good.
Travelers: Fun time traveling show from Canada. Been on a couple seasons, very entertaining.
