Train

I enjoyed this series more than I expected. The plot is gripping from start to finish. I was constantly wondering what will happen next. Of all the Korean dramas I've watched, able to maintain an atmosphere of suspense with an intricate and interesting plot is rare. Most series seem to lose its suspense or begin to drag on with inconsist story progression or stupid character decision. Train surpringly managed to overcome some of these elements and keep its pace. Though some of the scenerios are very dramatic and is melodramatic, but the mysterious atmosphere kept me glued to the screen.

Overall really enjoyed it as it is very thrilling.

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.

I must admit that I was confused during the first five or so episodes but was intrigued enough to stay with it.

I am happy I did because the story began to unravel and make sense after that. Much suspension of disbelief is required but then again, this is a sci fi/fantasy show so a lot of creative license was used.

Actors turned in good performances. I last saw the female lead as half of the second couple in Weightlifting Kim Bok-joo. Male lead in this show was very convincing as good cop/bad cop. This show is recommendable to those who love suspense, crime, whodunnit shows.

12 episodes were well-utilized. The team thought well enough not to force 16 episodes out if this.

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.

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.
