Wrong person to answer that (I mostly watch older stuff), but currently watching Vikings. It's not super new, but the episodes I'm at were done within the last 5 years. The writing is a mish-mash of sagas, as well as creative liberty. What happens in the show and what the actors do on-screen is very realistic regarding actual human nature, with only mild romantization. The only flaws are an unnecessary blue tint on the camera and just a tad too much pointless drama (realistic, but I could use less).
Vikings is essentially Game of Thrones, with more realistic and down to earth.
