This series is so beyond the typical mystery BL that it almost feels unfair to put it in that category. The plotline is interesting and the romance is very heartfelt. The internal struggles of the characters is incredibly well done and though it seems predictable at first, there are many unexpected twists.

The mystery genre as a whole can be very hit or miss, plot twists are often so unexpected that they don't make sense with the story or characters, but Spare Me Your Mercy does it right. It subverts your expectations without breaking the flow of the story.

The cinematography is fantastic and adds to the eerie feeling, as does the music. Though I will say, there are some scenes where the music score is unnecessarily dramatic, but I guess it adds to the 'something bad could happen at any moment' vibe.

And the ending is truly one of the best endings I've ever seen. The show stays authentic to the characters and story until the very end. Every loose end gets wrapped up and I was left feeling completely satisfied.

There are a couple "oh my god, why would you do that?!"/"that's so stupid" moments but it wasn't enough to affect the viewing experience (at least for me). Also I know some of the medical practices aren't 100% accurate but it's probably close enough as long as you aren't using this drama to study for med school exams.
