1. Really liked the first half. The premise was interesting and i loved the it was action packed. The middle dragged though and story stopped making sense.
2. Loved Taesul and Seohae's team work and Taesul always has great ideas. But later on i thought Taesul's actions started getting conflicted when he fell in love with Seohae. He kept choosing the girl vs the world.
3. Loved Seohae and her dad.
4. Park's story and the Asia Mart team.
5. Taesan and Taesul's bromance esp that part when Taesan gave him the injection.

Dislikes
So many questions and not enough answers!!
1. No explanation of how the time travel works. Writers assume we understand the rules. We don't even know when the time loop started.
2. Sigma as a villain is lame. His reasons are not enough to blow up Korea. Eddy as the last minute bad guy felt forced.
3. Taesul's final decision just wasted everyone's efforts (and our 16 hours of watching)
4. Lots of unnecessary or wasted characters like Jaesun or that guy that keeps chasing after Seohae.
