Alright so I had extremely high hopes for this one because the sypnosis sounded so cool. Seriously, two detectives try to solve cold cases with a detective from the past using walkie-talkies. And knowing it's not one case but mutliple cases, it sounded promising, it won'thet noring they won't drag the subplots we get to see different criminals the way Hanyeong would profile them and use his 'skills' the whole new way of solving the case but the way it was underwhelming. So disappointed. It's not a bad show, sure it's interesting you want to know what would happen but the way the main idea was used very badly as, more of something at the side rather than the whole point of the show. First off, they didn't solve any cases together. Whenever someone discovered something and they tell it to the other, the other already knows about it. One of the two detectives in the future doesn't even know about the walkietalkie-future-past-communication until the 14th episode which takes away from how well it could've been. The only time she used the walkie-talkie was basically her crying the whole convo and getting sentimental.
The way each time they were on a case they each detective solved it on their own, they could do without each other. The potential this plotline could've had and it just missed it. Another thing was the characters' writing they were written very badly. I'm a person who cares more about the characters than the plot, I would watch a show with an okay plot if it had great characters and would drop a show of a good plot with bad characters. This show didn't have well-written characters or a good plot as I've previously mentioned. The characters are very one dimesional, it seems like they have no life outside of the cases they solve, no other acquaintances, nothing. Which made them seem very dull and unlikable in my opinion I couldn't stand them and the way some lines sounded so forced. Like all three detectives are made up of one personality. Righteous, wants to know the truth,have no sense of humour, no quirks absolutely zero personality besides that. Each time I watched an episode I was not very hooked or interested with what was going on and then it ends at an intense part so I go for the next episode only to be underwhelmed with the events as they unfold. The ending of the show didn't feel satisfying at all??? I know they tried to pull an open ending but it just seemed like everything is starting all over again with the whole confusion and repetitiveness of the whole plot all over again. Was not a fan.
I'd give it a 6.5 stars because it could be enjoyable to a lot of people I just feel it could've been done way better.
