Search is a rare gem of a drama. It's intense but not stressful. No boring moments, not a single weakness. There's action but the relationships between characters (including human-animal) are much more important. There are zombies but they have little screentime, there is a mystery to be solved. Zombie attacks are kept to a minimum so the suspense is more psychological than relying on shock effects. That makes it all the more interesting.

Altogether this has more a feel of a classic sci fi series (like the original Star Trek) than anything else. The characters are on a limited space, they have to fulfill missions, they are tested.

The crew of actors couldn't be better. An all-stars cast such as this is a rare and wonderful thing. They complement each other so well. Jand Dong Yoon is a great natural talent and it's great to see how much effort he has made to learn the dog handling. Krystal, Park Yoon, Lee Hyun Hook and Moon Young Hee - we gradually learn about their characters and backgrounds in a very satisfying way.

I didn't want to pause watching the series, it had me hooked for the full 10 hours. That was the perfect lenght too. The slowly revealed plot was well written. The romance is present as a possibility, it's not really essential to the drama. This is a decision that leaves a lot of room for viewers' anticipation and imagination which is more satisfactory often than showing explicit romance and using breakups as the sole plot moving devices. (The last sentence is a reminder to myself to look for similar OCN dramas).
