A really good crime investigation drama with just the right amount of humor! The first episode will hook you right in midway into the episode (so be patient until then) and then you won't be able to stop yourself from binging the remaining episodes. The cases are interesting and there are unique twists about the criminal that is a real surprise that you would have probably not seen coming. There are some plot holes if you think about it thoroughly but if you watch it straight ahead then you won't even notice. However, the little plot holes don't affect the case progression or the entire drama as a whole. The drama being 12 episodes also helped prevent the drama from being dragged and had the right amount of cases and humor. The chemistry between the main cast is also very good. Glad I waited until the drama finished to watch. The ending was also very satisfying so I am hoping that there will be another season with the cast.

What I liked:
1. Great interesting cases with very surprising twists
2. Plotline is consistent (with minor plot holes)
3. Superb acting!

What could have been better:
1. If the show actually explained the motives of the serial killers and normal murderers because that would have made the case more interesting to know why they started killing (like the last case- the utility knife cases). Some were explained, but vaguely, so it was hard to see why they killed in that way (the icebox cases)
2. If the main cast were working together as an investigative team more often rather than a few times, unlike what the title suggests. There were more instances of the PD working separately from the police although in the end they get to the same conclusions

Other than those points I mentioned, this was a very good watch for someone who enjoys investigation dramas with suspense and crime. Totally recommend this for anyone who loves watching a good crime drama solved by a smart team!
