It started with a lousy introduction that was too ambitious on paper and then began to jump between one plot after another until the end. There was a desperate need for a better coherent structure and pacing. The characters were more or less fine but, despite being one of the most important characters, the ghost lacked a better characterization to make her role more impactful. The last 1-2 episodes were fundamentally bad, their main purpose was to lay down a handful of new elements for an imaginary sequel. This is a bad common practice streaming services have been pulling since forever to keep hold of the viewers attention regardless if they were planning for a sequel or not. The only acceptable scenario for such a practice is to have a direct sequel to follow it. Anyway, the drama was very mediocre Sci-Fi with a handful of failures.

First let me start by saying I really appreciate there being an English version to watch. It's hard to watch subtitles for an extended period of time. I wish more foreign films would offer this option. I'd bet a lot more English speakers would watch the show providing they know it's an option. I just happened to try to watch it and thought I would have to deal with subtitles. What a pleasant surprise to find out that I do not. I am a lover of sci-fi so this is right up my alley. I just started watching the series yesterday and it has caught my interest. I am enjoying watching it. It's got a medium action flow to it. If you like sci-fi mystery then this is the show for you.

Only saw one ep for now-but wow--superb wish uk did drama like this instead of reality rubbish every night--korea seem to have decent drama every single day-cant wait to watch full series-and of course the next series they have or movie--wish i spoke korean i could watch way more.

I loved it, there were moments when the drama got me a little confused, but I think they have done a good production job, they handled the special effects very well, the actors played their roles very well, the series did not focus on too many advanced technologies , I like it better that they are less excessive, sometimes too many fictional details distract the viewer from following the story.

I don't think the budget for this series was high, it's a shame that the marks on the cars couldn't be seen, in those details I feel that a bit of realism is lost. And finally, the last chapter was very crazy, many ups and downs, the end I did not understand much but I still enjoyed it.

This is clearly a well-budgeted and well-made show.

However, I was left feeling out of place with it constantly. Maybe it's my fault - I did watch it sporadically so I kept having to catch up with the thread of the story.

Nevertheless I just didn't connect with it and didn't feel the sense of danger that (I presume) I was supposed to feel.

The acting is fine and it's full of nice shots and cinematography. But it all felt very clinical - even with the subtitles (I find dubbing often puts me off) and left me baffled why I should care.

A complex story really needs to get you involved and this one doesn't. So you're left with no reason to invest the time. However, I did manage to watch the entire show, but the final episodes felt more like a duty than a fun.

If they do a second series I may give it a try... there are the seeds of a good show in there.
