I see that for some people the story felt like going back and forth between present time and joseon era in maybe a tiring way; for me, it kept the storyline pretty interesting, and helped to understand some context and the connection of some things. Sacrifice, suffering, and love would be the three main things I saw throughout the serie, in a good way. Also, loved the lesson of not letting "fate" define your whole life when you are the main responsible for how you conduct your life.
I actually enjoyed "My Royal Nemesis", and would say it's worth it to give it a try.
