This is like The Emperor's New Clothes. Like why is everyone praising this show? I would love to know what stood out so magnificently from this that everyone is throwing up their guts praising this. This show is probably one of the most pointless drivel I have watched since I started watching Kdramas. The only reason this isn't a 0 out of 10 stars is that: 1) Production was good, 2) The character of Death was okay, and 3) Episode 4 was actually good.

Summary: Dude kills himself. Get punished to die 12 times again. But he's given the chance to try and save himself and live as that body. Then he proceeds to be an idiot 12 times in a row. 12 times is not enough. This dude should just be punished to die over and over for eternity. How is he so stupid and selfish and annoying and-

Plot: The premise is interesting but the execution is so far from good that it makes the premise sound stupid too. There's no proper stake here. You would think eternal damnation vs. a chance to reinvent yourself would be such a simple and driven goal, right? Wrong! Because the main character makes no move to actually save himself. The lives are too short, too so you end up not really connecting with any of these characters. What we learn about them is thrown at us as exposition in little montages. That is just unimpressive. The relationships that could be invested in like the girlfriend and the mother are not there long enough for it to go anywhere. The personalities are disjointed, especially in case of male lead who first comes across as a simple and dejected young man but through out the reincarnations or whatever you call it, he's just a greedy, pathetic, selfish loser who wastes every chance he's given, never tries to guard the precious lives in his hands and instead focuses on power trips he was denied in his first life and money. Why would you root for such a character? A jerk. And the reincarnations aren't better either. With the exception of the the kids and the last one, the others are just nothing characters. Bland. I couldn't care about any plot point because all I was focused on was saving these lives and this dude was into everything but that. That's a dissonance between what drives the character and what you as a viewer want from this show. As a result, it was a dissatisfying watch with very very VERY annoying beats. Plus, most of the show is just focused on nonsensical, sensationalized fight scenes or special affects moments which while impressive as a production fact, didn't really add flesh to this flimsy plot. Episode 4 was slightly better but having watched episode five since then, I know that the show did nothing with what was built in that episode so the potential for any character development was wasted away too. Making even that one good episode feel like a pointless blip.

Acting: This show is stacked with heavy weight actors. What a waste!

Music and production: Music was, I don't know, okay? The production value is very high. But this is a classic case of sacrificing substance for technicalities. The show is made with high technological value but what's the point of all that pomp and ceremony when the plot is nonsense and weak?

Rewatch value: None

Negatives: Everything.

Overall: I don't know, if you liked this, we probably have vastly different taste and could never recommend anything to each other. I hated this. Awful. Horrible.
Edit: You wanna read my part 2 review too...trust me!
