TV nerds: what should I watch

I haven't watched TV in years; kids and my previous job really killed that.

There's SO much out there since I last picked up a remote, and I have a fucking huge backlog.

I'm open to anything, as long as it's well done.

Series I liked: Vikings, Norsemen (hysterical), The Americans, GoT, Man in the High Castle, Expanse, Spartacus (Batiartus is amazing)

I'm scratching the surface of Boardwalk Empire, but open to other rabbit holes.
