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.

I really need someone to explain to me what happened in the last episode especially the last 15 minutes!!!! 😭😭 I loved the mystery that was found in the drama, but can't give it 10 stars because I didn't understand anything literally 😭😭😭

This series was probably 3 episodes too long. The first six/seven episodes flowed nicely, and I felt, were engaging. I felt episodes 8 and 9 were just efforts to extend the story. Still entertaining, but, much less so than the previous episodes. Then you had the last episode...Lord...As others have remarked, the last episode made no sense. I just finished watching it and I am totally confused. The story up until the end was original. As with most Korean movies/series, the acting was great. I deducted stars from my rating for the above reasons. Just go in knowing you will be shaking your head at the ending.

THE ENDING EXPLAINED !!! ( A bit spoilers alert )

The ghost and masked man materialize there at the time. While the agents are informed about the existence of the Ghost, the moment they are about to start firing, the two create two force fields and pause the time. The Ghost telepathically speaks with Sae-Byeok and asks whether she came to save Sae-Ha, and the answer becomes pretty self-evident.

After this devastating sequence, we see Eo-Jin dropping Sae-Byeok off at her house and later having a heartfelt conversation with her. He also learns that he had died in an alternate timeline, and Sae-Ha sacrificed himself to save him. Cut to a year later, where we see Sae-Byeok with her kid. Eo-Jin suddenly drops in and urges her to tag along with her. He even knows her daughter's name, which surprises her since they hadn't spoken about the daughter. He mentions that she told him the name, which indicates perhaps Eo-Jin has come there from a different timeline.

While they drive off, the bureau's buildings get engulfed in flames after a flash of blue light hits them. When the two reach a warehouse, the door opens to show Sae-Ha, and the Ghost comes out, and then all of them enter this place. The ending, like any other episode from the season, ends on a cliffhanger. Besides an effort to save herself (since she is connected to Sae-Byeok through ancestry), there is hardly any more conclusion I can gather from the scene.
