When Jo In Sung received an invitation to star in this series, he thought it was "just another superhero story" and wanted to turn down the offer. But after he read the script, he was greatly impressed and joined the project right away. What some of us thought was going to be a generic Korean version of Avengers turned out to be so much more than that.

Moving, at its very core, is a story about humans and humanity. It is also a story about parenting, brotherhood, teen angst, love, betrayal, finding who you are and where you're going, moral gray zones... everything that we as real people could relate to. That's how realistic the characters and their struggles were.

The thing I love most about this drama is that, although the story centers around superheroes, at the end of the day, they are "only human". Although the characters have extraordinary powers, they still struggle with life, relationships, moral choices, and will, if not more than the average person due to their awful circumstances. The worldview is grim and realistic, people are used as tools and must do things they don't want to do just to survive in this world, and every choice to deviate from that path takes courage and sacrifices. This is a prevalent theme to most characters in the drama, even some of the "antagonists". Every character has a well thought out backstory to them that tells you lessons about life, and that takes a lot of empathy from the writer. It is an absolutely phenomenal and unique take to the already saturated superhero genre.

I can't pinpoint who the main character in the story is because they are all main characters and share almost equal weight and screentime. The acting is top notch, especially for the older generation actors. They had to play themselves in the present time, as well as their younger counterparts. You could see them changing through time and hardships.

Plot-wise, the structure has a clarity to it - about 7 episodes are allocated to present time, which talks about the younger generation (high school romance, teen self-searching, generational conflict). 7+ other episodes are allocated to the past, where the parents take the spotlight and we are hit with very harsh realities (manipulation, betrayal, social stigma, child protection). Depending on taste, an audience might favor one of these segment over another, but they may also love both. The last few episodes are wrapped up with edge-of-your-seat action sequences by an ensemble of casts.

I highly recommend this drama for anyone who is still hesitating. It is one of the best dramas to come out this year, and one of the most unique K-dramas to come out in these 20 years. Don't miss it!
