First of all, let me congratulate my dear Saint for building his own production house Idolfactory after all the hardships and criticisms he faced. He is giving a tough competition to all those big production houses.
So, let me talk about the premises: The story is set in a special forces academy at first, which is a very rare scenario in a Thai series. It showed the intensive training of the cops. Next, the characters become cops and are a part of an investigative defense force, so they deal with the cases. Their analytical thinking and problem-solving skills outshines here. The main base for the series is the Hindu mythological story of Naga(snake) and Garuda(eagle). As an Hindu, I knew all about the rivalry between Naga and Garuda and I really thank Idolfactory for spreading our culture and stories through this series. It was so fun to watch the stories I only heard of.
Billy and Babe did an incredible job as the main leads. Billy had improved his acting skills so much and Babe was a rookie but still slayed the role. Heng as the villain rocked....he needs to win the best villain award. Gap as the brother Yai won my heart. All the side characters and guest roles did their jobs perfectly...that's why the series is so flawless. I love how along with each case we came to know more about art, drugs, sexual abuse and so on. The series dealt with numerous social issues with each episode. What astonishes me the most this series has every genre in it - crime, thriller, mystery, romance, comedy, myth, suspense, but yet everything is blended properly. Most of the series fail when it comes to plot execution because they tried to include more genres, but The Sign succeeded in doing so. You can literally feel the hard work that was put behind to create this show.
The visuals was such an eye-candy and all the aesthetics was so pleasing. The CGI team needs a raise, because that was Hollywood-level VFX. The flow of the story and editing was impressive. I have a ton of scenes that has beautiful shots and transitions. Every scene was unskippable and interesting. I loved the cliffhanger ending too.
The OST always sends shivers down my spine. I don't know why. It has some kind of power to it.
Overall a must watch. You are missing out on a great series if you haven't watched this yet. Even if you don't like BLs, trust me you should watch this series and you will never ever regret it. I WANT TO RATE THIS 1000/10.
