I have learned with time to lower my expectations so I can be pleasantly surprised. Saying that, the poster for this drama intrigued me and the plot sounded interesting, the first episode surprised me and overall the story was very well-written and unique, but there was always something that bothered me.

I understand that they were going full out with the special effects, the story was daring and hard to adapt to the small screen, so it was a huge risk taken by the company. But it annoyed me that they didn't dedicate more of screentime to the flashback scenes, even in the present it felt too much that I was being told what happened instead of showed what happened and I'm a visual person, so it really made a difference to me.

I loved the build up of the main couple, flirting and bickering being my favorite dynamic, up until the point that they consumate their love, I can't really explain why, I don't think it was either the director or actors' fault, as they still delivered masterfully done love scenes, but the writing did feel a little bit lackluster at times and I stopped being pulled by their epic love story, what was bad for me since it was the main point of the story.

I didn't really care for the secondary couple, they couldn't even work as a comic relief for me. Yai was the highlight of the series, he was not just a great friend and a wonderful boyfriend, the support he gave Tharn warmed my heart and I really believed in their bond, he was ultimately a great person.

Heng Asavarid was giving it as the villain Chalothon, but unfortunately Chalothon didn't give much as the main antagonist making his redemption very undeserving.

For that and other reason I say, The Sign gave a lot to the genre, it was an audacious adventure with a lot of heart and a pinch of experience. It was beautiful, but for me, it was incomplete. Making it a good start, but hopefully, not the best fantasy BL we will ever see.
