A very disappointing drama. Indeed, I was expecting a lot since I saw all good reviews about this drama and since I was looking forward to watching another "locked room" series, but even if I watched this drama with zero expectations, I still wouldn't have liked it.

The female lead is supposed to be clever but I don't feel it at all. She just uses her uncle's position to get whatever she wants and gets away with it. Plus it's absurd how she and Saikawa-sensei winds up in every crime scene.
Plus what's with that weird trance Saikawa-sensei goes into before he figures out each case? Lol, it looked kind of silly..

I don't like the individual cases either. Well the 1st case was pretty good but then it starts getting progressively worse from there onwards. The 3rd case and the last case, both involving Dr Magata Shiki were the most ridiculous ones. I don't get why the two leads are so obsessed with her.
There were a few ideas in the other cases that were kind of good but overall it was a hot mess.

This drama is just over-hyped, in my opinion.
