I liked the first season and didn't know tell you why I haven't seen the remaining three.
I think each season treats the missions differently, it doesn't try to be repetitive, I say this because according to the second season it differs in action from the first.
I think after I finish Rings of Power, I will pick up the Jack Ryan series.
I have always tried to give Rings of Power a fair shake but I struggled to make it through entire episodes of season 2 of that.
I've heard good opinions about the second season, but I've yet to see half of the first and that's holding me back with this series.
The 2nd season is indeed better than the 1st but that is not as much of a compliment as it sounds like it is. I felt the 1st season was nearly unbearable for anyone that is a fan of the books or the Jackson trilogy.
