If you're like me and you hate flashbacks, you probably won't like this drama.

Acting/Cast: Top notch easily. Great cast, great acting. The acting made me feel things, especially in the first half of the drama. 10/10

Writing: The writing was great in the 1st half. I liked the story between Bong Seok and his mom. I found the kids to be interesting and how they each deal with their "condition". This isn't really about superheroes...they're more like everyday people that have an ability that has made them outcasts. I found that approach to be compelling. It reminded me of the plot of a book I read in school called Hidden Talents by David Lubar. So, in the beginning, when the focus was on the kids in this school together, I really enjoyed it. Then, the story went into flashback mode that lasted for way too long. The story wasn't very linear anymore and it jumped between characters. Because of this jumping around, many characters that I enjoyed watching were completely absent from multiple episodes in a row. I just wanted the flashback to hurry up so I could get back to watching the kids at the school. Don't get me wrong, the adults had interesting stories too, but they were dragged out for way too long. I almost dropped this drama because of this. They should have cut back to the kids in the middle of the flashbacks or maybe cut the total number of episodes down. Towards the end, a character was introduced, given a back story in flashback fashion and everything. It seemed out-of-place. Why spend so much time on an insignificant character this late in the drama? I guess it was to give the characters connected to him a little bit of background and humanize some of the "villains"? Maybe if they didn't drag out the flashbacks of the 2 main kids' parents, they could have had more time to appropriately flesh out some of these side characters. However, despite almost dropping this drama in the 2nd half, the ending was decent. 6/10

Direction/SFX/Music: I didn’t like the flow/pacing of the drama. Flashbacks lasted so long that I nearly forgot what the faces of characters on the backburner looked like. However, the production value was obviously high. Most of the time, the SFX was very well done. However, there were some flying scenes that I thought didn't look so great. The music didn’t grab my attention, but at least it didn’t annoy me. 5/10

Entertainment Value: The first half kept me engaged. It was emotional and unique. I found myself looking for a plot but instead, I got a barrage of flashbacks. The story dragged on, and I longed for the simpler times that took place within the school for extraordinary children…which did eventually come around again, but too little, too late. 3.5/10

Overall, I gave this drama a 6/10 mainly due to my hatred for flashbacks.
