My pick for best series of 2019 is:
Yellowstone. It's the best series I saw in 2019 and the best series I saw in 2018! I think Yellowstone just blows away any of the other new shows I've seen. Kevin Costner does a tremendous job portraying John Dutton, a rancher who is doing everything he can to protect his ranch from a variety of low-lifes who want to take it away from him. John Dutton has two sons and a daughter, as well as a grandson. They had what I thought was leading up to a cliffhanger ending for this season regarding the grandson. I didn't think they were going to let us know what happens to the kid until next season.
There was an episode this past season regarding his daughter which was probably the most graphically violent beating of a woman I've seen on TV or in a movie. They're certainly not afraid to push the limits of good taste on Yellowstone, but I've got to say that scene was remarkably well acted by Kelly Reilly. I liked the way Beth Dutton stayed so tough during the whole ordeal, never giving them the satisfaction of seeing her break down.
Yellowstone is doing so well that they say they're probably going to have quite a few more seasons of it, which is more than originally planned. Season three is renewed for 10 more seasons. That's my only complaint about the show - why do they keep making these tiny little mini-seasons? It used to that all the shows ran from fall to spring and just took the summer off. Yellowstone's a great show but they take too damn much time off!
