This drama elicits strong opinions from viewers, whether positive or negative. I fall into the positive opinion camp.

I love how well the story is written, it is tightly scripted and out of the few lakorns I've watched, it is the best written so far, it even beats some kdramas and cdramas that I've watched in that the intention of the show is fully realised by the end of the story, the story doesn't meander here and there, it's just straightforward and clean, this is so rare in drama writing.

The story itself, the disconcerting and uncomfortable aspects of it, were written in a way to illustrate the end goal of the story which is that love is an action, it needs to be demonstrated, it's selfless and it has the power to transform a person's life and literally heal their heart. Love is redemptive.
The show did a pretty good job of showing this from start to finish. I don't like to enter into debates about social issues, abuse, evil deeds etc, I take what a drama is trying to communicate to me and if the story is told effectively then good, if not I drop it, simple. Sawan Biang is a story very well told.

Another reason why this drama succeeded in communicating its story so well is the acting. The acting is phenomenal!
Ken Theeradeth as Kawee is so amazingly nuanced, his facial expressions, his body language, the tone of his voice are all communication tools that he uses to great effect, sometimes he didn't even need to say anything and you could see that he was hurting, conflicted, crying out for some affection and attention. Ken's portrayal of Kawee is so good that even though he does such hateful and hurtful things to the people around him and especially to Narin, as a viewer I harboured inordinate amounts of sympathy for him, I got where he was coming from and why he was lashing out, I may not agree with his methods of lashing out but I got him, and that's what the writers are communicating: cause and effect.

Anne Thongprasom's rendition of Narin is so poignant and heartfelt, I felt all her emotions, from innocent carefree confidence to fear, bewilderment, pain, disbelief, hate and love. Her acting had a self assured realism that just grabbed you and wouldn't let go. The combination of Anne and Ken is what made this drama even halfway watchable, in the hands of lesser actors this storyline and premise would have been a complete disaster.

Other notable cast mentions are the actor who played Kid, (Kawee's father) and the actress who played Leela (Narin's sister and Kid's wife)
Kid appeared to be so clueless in the beginning to the extent that I despised him for the way he raised his son, but in the end his character self actualised and came full circle, his steady character was a perfect foil to the more volatile Leela and Kawee.
The role of Leela was expertly portrayed, I found that Leela was suitably complex in that she had an old wound that never healed, a hurt and pain that she never resolved, as a result she seemed all over the place and was vindictive and spiteful. In the end though she also came full circle and realised the unhealthy part she played in the awful events that took place between Kawee and Narin.

The other supporting cast was good and helped the story along, they weren't just annoying nuisances as you will find in many Lakorns.

Overall this drama set out to tell a story about a damaged, childish, spoilt and destructive man who during the course of his destructive behaviour fell in love, dug deep and resolved to humble himself and make penance for his wrongdoing, and this story was well told.

Overall score 9
