NON SPOILER REVIEW :

The drama of the year contender. ( Beware to read other reviews coz this drama has major spoilers everywhere else which is why it's difficult to write a review like this, You don't wanna spoil the fun of watching this gem)
This has to be one of the best-diversifying themes I've watched.
Zero Plot holes!
PLOT: This drama has the absolute best use of time travelling.
Especially the sequence of the consequences.
I swear whoever has written this is a genius.
Simply tempting to watch this.
It does start off slowly with the 1st episode not giving away much, so you've to stick to it.
But this makes you feel every bit of it.
Once it gets into the flow, it leaves you speechless for what's going on.
This is why I love the Taiwanese industry.
They make such a drama every 2-3 years which just takes your breath away.

ACTING: It was a bit off at some moments( Maybe coz it felt so surreal that I found it a bit off xD) but nonetheless full of pure excellence.

Direction: This is the main part. The director and every other member knew what they wanted to show, this is a drama that could only have attained excellence had it done everything right. And guess what! The hell they eventually did.

Overall: Still reading my review? The hell you doing, go and watch this gem ^^
