I reviewed the first half of the drama, and it was for the entirety of the drama. So, here, I'll give the Cliff's Notes version of my thoughts.

My recommendation would be watch it and decide for yourself, since everyone seems to have loved this drama. My rating is based on my feelings and does not reflect the actual quality of the drama.

Excellent cast. If you've been watching Korean dramas for any period of time, these faces will be familiar to you. I would have liked for some of the stories to have been more in depth, to develop the characters a little better. This drama was a Who's Who in drama land.

The concept was interesting. Some people had a problem that it seemed to be an anti-suicide PSA, but to me it was more about how choices we make affect others.

My biggest problem with this drama was the overabundance of violence. Many of the characters were not well developed, because of the number of bodies that he inhabited in eight short episodes.

But again, I will say, this is all just my personal opinion. Watch it, you'll probably like it.
