Overall: I appreciated the premise and production value; however, I thought there could have been improvements with the plots/characters. Adapted from the book Euthanasia: Spare Me Your Mercy by Sammon which I haven't read and I reviewed this series on its own merits. 8 episodes about 45 minutes each. Aired uncut on iQIYI https://www.iq.com/play/spare-me-your-mercy-episode-1-1e3q3w4ts14?lang=en_us and cut on One31 YouTube channel (not in Japan, Korea, Taiwan or Thailand) https://youtube.com/playlist?list=PLXopbKxiivxrgJk-EvQLFVdakJlFviiix&si=aaqj7i0CX2sAeIVP - the first episode cut version was about 1 minute shorter than the uncut version.

Content Warnings: there were several major ones in the first episode and in subsequent episodes, but I kept this review spoiler free

What I Liked
- unique premise
- mystery element
- countryside setting
- discussed the ethics of someone making choices about their life, including at the end of their life
- production value

Room For Improvement
- the first scene as a character set up/voice over exposition dump, subsequent exposition dumps
- stupid characters/actions that felt "because the writer said so"
- reveals happened too early
- chemistry felt hot/cold, wasn't sold on the romance aspect
- the open ending
