First i like the beaty and the beast storyline.

The idea is fresh and i was so hyped after the first episode just unbelievable. Love the message of the film and the romance between FL and ML. A sweet and soft romance. I love the cast and acting. Music is quit nice and fit the scenes. I will rewatch the first episodes many times.

unfortunately the writer didn't pay much attention to character development from the middle on, so I think that many decisions are not true to character. Also, some events are never thought-out enough. the Series could have been longer, unusual for a Thai drama.

So now more detailed:
The ML is always on point. Nonta (for me the second ML) is it most times. I like the male character more because they are more on point and have more character than the female ones. I have the feeling the person who wrote the script wanted certain plots and made the female characters act strangely therefore.
I can't understand the reactions of the FL sometimes. She is smart beatyful and know nature, but sometimes her reactions is quite the opposite. Kahlongs (for me the second FL) character isn't understandebale at all, to innocent for where she lives.
Dr. Atchara could have been cut out or given more meaning, same for Fon. Euang i don't know what to think of her.
the whole setting isn't worked out well enough.

For the Plot:
I hate the scared FL that make only mistakes from a certain episode on. At the beginning she is smart and help a lot, but at some points she is stupid and i don't know why. She could have beeen more importent for the spirit and ML get together in harmony part. She could have understand him and helped him understand what he is and how to connected. then they are separated by the misunderstanding because of his ex. And not as it is shown, as soon as she knows what he is, she is only afraid of him and later on, enchantment: the fear is gone.
I also hate that no one knows something about the Tigerking from the tribe. When i as a viewer understand how the spirit is passed on, without any indication, why not the characters too. And that the dagger was not destroyed.
I am not a fan of the Nonta and Kahlong as a romance couple.

So all in all there is room for improvement. But i loved it.
