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.

I didn't expect to like this series at all, but decided to watch it as it has the same lead actor as "Psychopath Diary". I wasn't disappointed and found this show entertaining.

This show has a relatively unique plot (similar to "Tunnel" or "Signal" but this time across universes). Unlike the American "Fringe" which also deals with multiple universes, this series stays very human and character-driven, and doesn't go off into a technical apocalyptic dystopia like so many US shows.

The lead character cast is strong and their performances are outstanding.

I like how they made the point of little decisions, when accumulated, leading us on vastly different life paths.

The show does suffer from a few unfortunate tropes though:

• Endless flashback to literally the same memories, and overlapping episode endings/beginnings. I found myself becoming good friends with the "skip" button. There's probably a few episodes worth of literally 100% repeated footage.

• The standard thriller tricks of a character going to explore abandoned buildings at night, in the dark, after learning that the armed criminal is there, without telling anyone where they're going or asking for backup. This cliche appears so much because that's what normal humans apparently do, right?

• A bit over-dramatic for my tastes at times. These endless hard stares, criminals monologuing for minutes on end before pressing the trigger, protagonists turning their backs on wounded enemies to cry and hug so the enemies could attack them again or escape, statements full of pathos, it's all here.

Overall, an excellent experience which could have been made much tighter by eliminating 90% of repetitions.

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

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.

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.
