Prodution wise, yes it is that good. The cinematography is the best among all dramas I have seen (watching on a big TV everything is just gorgeous), the comedy/drama/action is very well balanced, the main lead's chemestry is quite alluring... overall characters and locations are really well designed, story is solid. The weakest point is the pacing in the last few episodes and the underwhelming politcal plot.
im not that into historical dramas ive barely watched 1 so should i start this one or not?
The cinematography is excellent I could watch it only for that. Main couple chemistry is natural and everyone in the main cast is eye candy. If you are not into historicals just skip the political/palace scenes and you will be fine.
Edit: just checked for West is going to Paramount+
