re: Is Yellowstone Worth a Watch?

Agreed. The show itself is a very bad wannabe cowboy ripoff of the Godfather.
Kelly Reilly is actually the worst aspect of the show by a lot, and that's saying something with all the fake Eastwood types on the show.

Cole Hauser and the scenery are the only good parts of the show, yet that's good enough to kind of hook you.

If you want to sit through 3 seasons of mediocre storylines, some really badly drawn out characters, with top notch landscapes and horses, by all means go ahead.

If you are expecting a cowboy Breaking Bad or Sopranos level crime-ish drama, this ain't it.
