What a great show. I was sucked in immediately: this is exciting, funny yet also heartfelt from the outset. The characters pop off the screen and get you engaged right away. The greatest strength of this show is the complexity of its characters and relationships. As far fetched as the premise and plot can get, and the show doesn't even bother getting into the nitty gritty details of how the science would work, there is a core of psychological authenticity to how the characters interact.

Nam Shin III is the most adorable marshmallow of a character ever, and I loved how the FL was won over by him and was able to open her heart after the adversity she had dealt with earlier in life. Watching them grow together and fall in love was so sweet, I swooned hard. The typical evil chaebol shenanigans were well executed. Supporting characters were also rich and layered.

I thought this could be a 10/10 but it slightly fumbled the bag in the last 10 minutes of the last episode (Human Shin has a random two minute redemption arc? Nope, don't buy it. Evil Henchman is totally chill in prison after his 30 years of evil schemes amount to nothing, nope, that's not how that would go. Why wasn't the FL informed that the ML was being repaired, everyone just let her mourn for a year wtf?). Minor quibbles though, this show was awesome.
