I like it, but it's not a GoT. GoT was wayyyyy more complex with different story arcs. TLK is mostly following the story of one main protagonist. It's missing the complicated ethical dilemmas that GoT was great at. The speed of stories developing is also a lot quicker than GoT seasons 1-4, so TLK feels rushed. Finally, the writing, dialogue in particular, isnt as good. GoT has some amazing dialogues and character building.
On the other hand, it does make some neat political commentary that was missing from GoT, especially regarding religion. Another minor thing I liked were the accents. It's also missing a lot of the fantasy stuff (e.g. no dragons). Lastly, while the story itself is fiction, the overall trajectory and setting aligns with actual history. This made me interested in learning the related history which I knew nothing about.
What they do share is the medieval setting and political maneuvering of the time.They also both include traumatic scenes that are typically not shown in other shows.
Overall though, I like it and suggest that you give it a few episodes to try out. Like GoT, it took me a few episodes to really get into it, but then I was hooked.
