So far the most well executed drama of its genre in my opinion. I waited a long time for this and worried that it would be too draggy, yet it delivered more than expected.

The concept is nothing new but this one is exceptionally well executed. Each repeats were 'useful' without feeling like too much of a coincidence. It was TIGHT without feeling prearranged, something that a lot of inception movies and series fail to do. They were smart in that no ends are ever loose because every lives are important and they sold that point.

The main characters were great, dumbness was NEVER a plot device in this drama, and I thank the scriptwriter for that. Zhao Jinmai's acting was exceptionally stellar, Bai Jing Ting did good as expected. For the rest of the casts, Lao Zhang was played so charismatically, Lu Di's part acting could be improved but he was a lovable character.

I don't think any of the music stand out to me (FL would beg to differ lol). But at least nothing felt out of place.
The -0.5 is for the 2 episodes towards the end, don't get me wrong, the ending did the drama justice, but the last 2 episodes did falter a bit.

But hooray that it didn't drag, that's such a breakthrough especially in c-drama scene, I hope more will follow suit and respect the story like this instead of ordering more filler episodes to make the budget worth.
