I watched this k-drama in anticipation for Lee Joon Gi's fanmeeting in Kuala Lumpur on 22 September, which I bought a ticket.

What I liked:
1. Acting - Brilliant performance by Lee Joon Gi and Lee Kyung Young. It's great to see some character growth in Kim Hee Woo - Lee Joon Gi could show some range when Hee Woo was ungrateful teen-aged brat who then grew to be tactical fighter against injustice. LJG performance nicely complements Lee Kyung Young's cunning, corrupted politician character. Solid performance from Kim Chul Ki, Kim Jae Kyung & Ji Chan too.
2. Side characters - I like that supporting characters lasted more than 1 or 2 episodes - they all played an integral role in the fight against corruption. There were many supporting characters I like e.g. Park Sang Man, Kim Han Mi, Prosecutor Jeon Seok Gyu, Ji Seong ho and the old real estate guy who became Hee Woo's mentor.
3. Plot - I like the plot twists. Kim Seok Hoon is such unpredictable character and that reveal in episode 15 I did not see it coming!
4. Action scenes - Good choregraphed fight scenes and LJG really looked fit despite the lean/slender build.

What I disliked:
1. The afterlife/re-do connection - I understand why Hee Woo was given a re-do but I don't understand the process from Director Han to Hee Woo in episode 1 or 2 helipad scene.
2. The romance - Wow, Hee Woo has 3 romantic interest. I understand why romance arc is not explored much in this series but it'd be great if there were meaningful scenes that hinted at possible romance e.g. she told Hee Woo to share the burden because it's exhausting to fight injustice on his own.

Favourite scene:
Kim Hee Won's fight scenes with Doctor K
