If, like me, you wanted to drop it around episode 3, keep watching, because it gets so much better.

I have to admit, mixing variety show and drama was not a stupid idea. If produced correctly, it combines all the best aspects of the two entertainment media. Did it work out here? Yes and No.

Yes
The cast members trying to fit into the roles of detectives led to many funny scenes that quite literally made me cry from laughing a few times. Having the main plot link all the episodes made me more involved. Usually, with variety shows, I only watch the episodes that have guests I am interested in. Here, because they tried to tell a cohesive story, it "forces" me to watch all the episodes, to be able to understand what is going on.

Dramas and variety shows are as good as the chemistry between the characters/cast. Damn, they did a good job with the casting here. They played off of each other so well. No matter who was working with whom, and how they split up, it was always fun and entertaining to watch.

No
First three episodes were too scripted, to the point it did not feel genuine. Instead of watching the cast solve the mystery and play the games, it felt like I'm watching them act it out, as if they already knew all the answers. Luckily, even though they left the scripted parts for the plot line to progress, the solving cases did feel more organic in later episodes. They started to have fun with how cringe the show is and joke about it too.

Honestly, I was about to drop it in episode 3, and give it a last shot with 4th only because I saw who the guests were. I was lucky, because that episode changed my mind completely. Now I cannot wait to start watching season 2.
