Pros: Interesting storyline and plot
- love the grandfather and grandson interaction.
- the way history unfolds and you get to see how they incorporate it into the story
- fast paced
- Lee Sung Min definitely shone in this drama and has no doubt garnered even more fans after this

Cons:
- ML portraying himself as a student. Kdramas are mostly like this and sometimes, they can get away with it. Like the leads in Our Beloved Summer. Those two really looked good in their school uniforms.
- FL. Boring boring boring. Not only her looks, but also her fashion styling and her acting. Don't think she is cut out to be a lead.
From what I have seen in the comments online, many agree that she was not suitable for this role. Her line delivery is predictably boring. She can't even pass as a prosecutor. A male actor would have been better.
- Chaebols fighting over dominance and money. A frequent trope in kdramas. Different actors but still the same greed and money grubbing issues. A bit tiring in its repitiion, but SJK on screen is definitely a worthy watch
- The ending was a big DUH for me. I don't know the actual webtoon ending, but this one AAARRRGGHH... Seriously, is it just me who finds it weird that no one even wondered why Do Jun looked exactly like Hyun Woo????
