I didn't read anything about this ahead of time, and I'll be honest, I've no idea why I suddenly decided to watch something about traffic cops! I am so glad I did, though. I watched it on Hulu in the US.

First, there were multiple different cases in every couple of episodes, with an overarching mystery that is woven through each episode and finally solved at the end.

I LOVED the TCI team! They all made significant contributions to each of the cases, and you could tell they had a lot of respect for one another. I'm not a big fan of Lee Min Ki - he's the same character in each drama of his that I've seen. He did his usual job, and I really liked each of the other characters. They managed to make the two women smart and competent without being witchy. There were three actors that really departed from other works I've seen them in - Kang Gi Doong, Oi Eui Shik and Lee Yoo Joon. Hats off to them, especially Kang Gi Doong - wow, he was a piece of work!

I found the public service announcement at the end of each episode very interesting, with statistics about hit-and-run, drunk driving, etc.

The car chases were excellent.
No romance - thank you!
I'm not a big fan of shows that have a second season, but I'd be up for a season 2 from this show!
