It peaked with the season 3 finale of the Yellowstone being attacked and all the family left for dead. That was intense.
Season 4's only interesting storyline was Jimmy going to Texas to the 6's to learn how to cowboy. The rest of it was the garbage governor storyline, the introduction of Summer, Beth's corporate office job and just an overall lesser focus on the ranch and ranch hands. Beth is a full on cartoon character by season 5 and there is not one interesting aspect to the show anymore.
I'll still be interested to watch the finale season in the fall but only to see every one's fate.
