Before you start watching MPD, you have to be prepared for a wild ride. The drama is very fast-paced and action packed. There really wasn't one boring moment.

The characters were well-written and roles were successfully executed by actors. The chemistry between main leads was great, the same goes to their colleagues in the office.
Beside the main plot, I especially liked the part with the Private Pyun, he was so sweet and chill until... until he wasn't. The development of his story was quite unexpected, to say the least.

The fascinating aspect of this drama was a bizzare form of love between Noh Tae Nam and Noh Hwa Young. I just couldn't grasp it. I couldn't figure out NHY's real feelings and didn't understand why NTN was still trying to build a relationship at the end.

Now, there's this little thing that was hilarious to me. Generally, I don't pay a lot of attention to music in dramas, unless it is annoying. In this one music was fitting and one song will be added to my playlist, but...
~ the song in the outro ~ holy moly I loved it! There was this really intense build-up and cool bass, and suddenly some guy starts singing like a crazy-scientist-type villain in kids cartoons. It was so funny to me

Extra things:
+ the little marching song when there was a funny situation
+ scenes from the future with no context at the beginning of some episodes
+ the happy and giggly tailor
+ the cut-off leg - what the hell was that

Some things I didn't enjoy that much:
- some parts were ended too abruptly because of too many things happening at the same time
- the fast-forward to one year later at the last 10 minutes - this just seems lazy
- the dialogue between FL and her late father - made me feel weird
- conclusion of the main leads' relationship - the kiss seemed like a formality to let us know that they are now dating - come on, they spent more time on Noh Tae Nam feeding the dogs

Although this drama definitely wasn't perfect, it was a really fun experience and it will be on my soon-to-be-rewatched list
