It's a fine drama. I was emotionally involved in the story from the beginning almost to the end. The tense moments were tense, the protagonists were likable, and the attention to detail was high. However, near the end it slipped a bit.

Here's why.

I think the choice to focus on the motives of antagonists and the related case was bad. First, because their motives and the case were predictable, and they themselves weren't likable or sympathetic people like narrative wants us to feel. Second, because it dragged on too long, the last 2-3 episodes are about that rather then the loop and how to break it.

I also think that portrayal of police was too idealistic, all police officers were dedicated, kind, willing to risk their lives, zealous in their devotion and the phrase "trust the police" was told multiple times, then we were shown on multiple occasions that trusting the police is always the best idea. It felt like propaganda.

The ending "slideshow" showing the endings of various passengers was idealistic too, like what kinda guy would be happy to see his estranged former criminal father suddenly show up at work with a bunch of dirty watermelons? And the boomer parents cosplaying for the cat guy, I just laughed at that.

Also, speaking of the cat guy. He "rescues" cats from the street by putting them in cages and locking them in his small room in darkness. Tbh death is probably better then such rescue.

And the romance between main characters, literally zero chemistry.

Finally, the reason why time loop happened wasn't explained.

So I can't rate it higher then 8/10. There are much better time travel and time loop works of fiction around.
