Overall I really enjoyed the premise of this story. The medical experiment was a quick and easy way to show the extreme changes in the intelligence and strength of the character. And I really liked how they showed that rapid change. For my I liked how the drama showed that happiness isn't measured by how smart or strong you are but who you are enjoying your accomplishments with.

My main issue with the drama was the pacing. I think that having 6 episodes was perfect but I feel like they didn't utilize their time appropriately. The first 4 episodes were amazing but, for me, episode 5 lacked something (and i skipped some parts of it), and then episode six wrapped everything up too quickly. I really think that the content of the last 10 minutes of the finale should have been 20 minutes so we are the watcher could have more hope for the future for In Sung so there wouldn't have been such a harsh cut to the future. And maybe show more growth from him (in the things that he thinks he is lacking in.)
