Park Shin Hye steals the show as Kang Bitna, a judge who gets possessed by the demon judge Justicia after her death. She is a fashion star, crazy, violent and arrogant. But all of this is put together into a likeable character package, who makes you root for her brand of justice. The story revolves around her journey from being the devil who only cares about going back to hell to developing human emotions and understanding different perspectives. Bitna's lopsided smirk and crazy eyes when staring at those scummy criminals makes for the biggest highlight of the show.

Kim Jae-young as Han Daon had the perfect puppy-dog eyes that brought out the human in the demon. His heartbreaking origin story aside, but loosing another family member, the kind, tough as nails boss lady, was a bit too much. He perfectly emoted his struggle of wanting to be a good police officer but also setting aside everything and getting his revenge. I found the chemistry between the main leads to be a bit lacking, though the good looks on both sides made up for it.

I absolutely loved the ensemble cast. Every single one had stories to tell, however small, and brought depth to the overall plot. I was expecting to be moved by the stories of those left behind (was a big sucker for Taxi Driver for a similar reason), but seeing the cheery, church going landlady break down really got to me. I adored the old grandmother, i am just going to stop here, but her and Bitna's back and forth was such a treat to watch, provided a little light in between the pain.
The only major issue i had was the plot towards the end. I think it would have been better to have 2 more episodes, but make the ending, less rushed and more rational. Satan just being defeated like it's no big deal sort of undermined the story they set up, and the usually smart & meticulous J having a complete breakdown once confronted with a single problem felt a bit off. The guy just straigh up confessed in court, and even if arrogant and hateful, it felt forced just to give the families closure and justify Bitna's ultimate beatdown. I understand they wanted to focus on justice within the boundaries of law and human evil but still, I hoped there was a bit more to it.

Overall, definitely worth a watch. To more dramas where evil is punished, so people can live vicariously through them.
