Frist of all, u need to watch the first season in order to understand the second (this) one, it will be hella confusing if u don't.
Now about the series, I'd say i absolutely love it, one of my all time fav. The story line is awesome, the cast couldn't be any better and it contians loads of twists which is so thrilling. Its like a roller coaster of emotion, one second, u r feeling happy that pang is finally victorious then the other sec u feel pity that he lost so badly. As i said before, it contains many twists and i sometimes i feel chills on my whole body. Though i would say that i didn't like the ending, tbh it was horrible with everyone getting the power. Think how disastrous the world would become, i get that its for equality but thats too much. I wish they listned to future grace instead of cutting her off forever.
One thing that i didn't like was the screen time for the "main cast". Pang, wave and punn aren't the only mcs, poor namtarn, she came in the last episode. She was done dirty (i am saying this cause i like her acting and she didn't get do much in this series)
