Train

I'm not really a sci-fi fan, so I wasn't expecting much when I started this drama, but I was hooked from the start.

The drama moves smoothly, avoiding many plot holes that most of these dramas fall in, you'd expect you found one and it turns out to be part of the plan or an unexpected plot twist.

I've known Siyoon first from Psychopaths' Diary, so it took me the first 4 episodes to not laugh everytime he has a serious expression, but he's a good actor and did well in this role.

The only part I didn't like much was how rushed the ending felt. They left unexplained bits that don't affect the overall plot, but still made the last 20 minutes feel like the director was saying "You get the idea now, you'll figure it out". Which isn't so bad, it might have dragged a bit otherwise, so all in all, it's one of the best shows with that idea.

This is one the best sci-fi crime thriller drama from south korea. Also it's the best treat for world wide korean drama lovers. I can't wait for the next episodes. Never miss this experience. My rating is 9/10

Not kidding i don't want this drama to end. Oh my god, i have watched like 50 korean dramas, in fact, more. The direction is fine but the story really is the hero. The actor in the lead role does it so well. It is a treat to watch it.

Holy shit how is this drama so underrated?? It has a fantastic script, characters, actors, soundtrack, filming etc. I really enjoyed this. It's probably one of my favourite sci-fi/crime kdramas. Excellent acting form Yoon Siyoon also. Wooowwwwww. Don't give this one a miss. That's all I can say.

I really enjoyed this series, the acting and script is first rate... I have enjoyed all the time travel Korean shows but this one is the best, maybe cause it's 12 episodes only... The lead actors are superb and I have watched now about 25 plus Korean dramas and this us definitely near the top with Mr Sunshine, Misaeng, Heachi and Stranger. Definitely recommended this series
