Watching Stranger helps you understand the protagonist and the situation he finds himself in, but you can safely watch just this drama. The creators here have provided all the information you need to have fun and understand the plot and context. Although I admit, there are some moments that taste better if you know Stranger. So, it is worth watching the original series, but it is not necessary.

Having said that, I must say that for me this drama was a wonderful entertainment almost to the end. I have some objections to the last two episodes, which is why I hesitated and delayed with my review. They are not episodes so bad as to heavily lower the final rating, it's just that for me personally they were far from providing me with satisfaction. On the other hand, both in terms of acting, plot, character driving, character development, relationships between characters, cinematography, action, sense of humor and enjoyment, the first 8 episodes are a fun, energetic 10/10. The last two are 8/10, so the average has slipped. Oh, and the music, so strange in places, and so well suited to the scenes, I couldn't help but love it :) The drama also has plenty of scenes-gems, even the last two episodes I didn't like. So I wholeheartedly recommend it if you like dramas about prosecutors, or just about intelligent people. For me, this is the best drama of 2024 (and the last few years :) )
