I came upon this drama by looking for action cop dramas. The synopsis reeled me in.

This drama is about a car crash investigation team called TCI. They're looked down upon because investigating car crashes is beneath the other ranks in the police force but these guys made other the top notch divisions look like heavy amateurs.

Each an every episode didn't disappoint. This drama kept the continuity throughout the whole series. They didn't stray like other dramas tend to do.

The high speed chase scene was the best. I love car chases and this one had me realizing my fists were clinched throughout the whole car chase scene. I actually had nail divots in my hands!

I loved all the characters both good and bad. I will say the MML was a little annoying. That stoic character is the dumbest character choice Korea like to display and it's annoying. The MML had no life until he had several run-ins with the bad guys. I get irritated when they make a character pretend he has no emotions. It drains the life out of what the episode is all about. I also hate when a character who can actually fight in real life pretend they can't fight. But in this case I liked the way it was done. They didn't make the MML pretend to know how to fight over night. He took what he remembered in his trainings and used it.
Towards the last few episodes he forgot to pretend to be stoic and that was the part I enjoyed. I guess I'm annoyed by him in Behind Your Touch-which Korea who speak backwards is really Touch Your Behind, lol.

All of the supporting actors did an excellent job. They could fight, there were no slapstick characters-which I hate-and everybody stuck to their character choices.

I also mainly watched this series because it had a lot of actors in this that played in dramas that I actually like so I knew they were going to do well in this.

The cinematography was awesome. I wonder how many cars were destroyed in making this drama! The music was highly annoying! I wasn't a fan of that screeching guitar or that guy screaming the 'Crash' theme song.

I know people are clamoring for a second season and if they do would they be able to pull it off. I know some dramas that have second seasons usually flop-Uncanny Counter 2...I'm still disappointed with that one!
