"BOSSAM: STEAL THE FATE" overally is not something very good but it's moderately average and worth a one time watch. But Bossam indeed is a different kind of Sageuk (historical Kdrama) and let me first time tell why you should watch it.

1. The drama's basic plot is totally new. Bossam being an old Korean tradition could be something new for the natives but it's undoubtedly unknown to the huge number of int'l audiences.

2. The first of the drama basically is a romcom-story happening in the premise of a historical period. Royalty, Nobility and system, everything is related but politics and diplomacy have minimum involvement.

3. Be it joyous or melancholic, this drama has many warm poetic moments unlike other historicals which are full of tragedy with lots of angst.

4. Whatever amount of diplomacy has been shown in the script, it is very very skillfull. And it's like there's lot more diplomatic progression than wars and fights or stunts.

5. Jung Il Woo goes shirtless in the 1st episode itself showing his bulky transformation :p (not a spoiler at all) and that's quite a sight to witness. Also, he runs a lot in this drama.

STORY & SCREENWRITING:
Bossam is set up in the premise of Joseon era and is based on a age old traditional custom. Bossam basically is the forceful abduction of a widowed woman by wrapping them inside a sack and marrying them off with a man. Even though it has politics and diplomacy, as it should've since it's a sageuk, it has equal amount of warm slow-burn romance story and basic storyline involves cohabitation and mutualism. It's about how Bossam-ing a widowed woman by secret local peddlers changes the fate and lives of all the people involved as well as influences the entire system of a nation. The plot line development is very nice till the 8th episode with a vibe of uniqueness but after that a major revelation took place which changed the entire drama and made it a typical historical Kdrama where certain influential Minister is after the King's dethronement to get hold of the power. And after 10-11 episodes things become repetitive like someone plotting treason, scheming to kill another, preparing to defeat another in courtroom, rescuing someone in need, getting caught, etc etc... All these things happened back ti back in an alternative manner hence became boring and uninteresting to a certain level. They should rather have made it a 16 episode drama without dragging the story by writing the same thing over and over again.

DIRECTION & SCREENPLAY:
Well, it is the same as I described the story writing above. The screen-editing, organization of scenes and sound editing were pretty good till the major climax of 8th episode but after that the director could not do much given the script turned typical. It ain't that bad till the end though it could have been a lot better. So I would say the entire 2nd half is still finely bearable.

CAST & ACTING:
The casting for the respective characters is actually good. Jung Il Woo and Kwon Yu Ri picked a good script and justified their characters pretty much good. Other supporting characters were nice too but the problem is with the drama characters developed by the writer. The Female Lead showed a character development to a certain extent tbh but Jung Il Woo's character went downhill with a major revelation about his past. I expected a stronger him after the twist but the character instead lost it's essence. Shin Hyun Soo's character is very very annoying; he plays an important role in all the tragedy and helps the leads many a times, however he ruins many a thing in the 1st half of the story for his stubbornness and stupid desires. The little kid Ko Dong Ha who played Jung Il Woo's son did great in whatever he was given but after first half that pretty nice character didn't have many scenes and finally became lost towards the end. The supporting roles by Shin Dong Mi and Lee Joon Hyuk were pretty funny and compatible who made us laugh at many instances. Kim Tae Woo as the King has a complicated character. He gets charged up most of the times screaming and throwing things. Lee Jae Yong as the main antagonist played his character very very well and his acting his highly commendable.

OSTs:
To be very honest, there are plenty of OSTs and all of them are very good. Most of them depict either warmness or melancholy which were produced given the storyline. Even though the story becomes typical after the 1st half, the sound editing and OST organization is good. Special mention to the OSTs titled "Love Song", "Song of Destiny",
"Along the Trail", "Collar" and "Song of Bau". I loved especially "Song of Bau" which has a touch of traditional Korean music and it's so heart touching. "Angular Stone" is a track which is melodious and catchy one. Notably, in most of these songs traditional Korean musical instruments have been used.

There is no significant work of cinematography in the drama but the camera works is beautiful at places where they intended to capture hearts with the scene's warmness.

ENDING: It is rushed. I had a hunch from the ending of 18th episode that the last 2 episodes will be rushed in order to bring the drama to an end it did happen for which I wasn't surprised at all. I am okay with how the drama ended because at least that is reasonable but again I hope they would have ended it at 16th without dragging.

To be honest, I expected them to keep the storyline and screenplay as it is for the first half of the drama where they lived a common life staying in small houses, dealing with poverty and facing the odds together and. Even the kid's to part should be have been seen more. I would have loved to see the entire drama as a modern day story happening in a historical period with least politics, that'd have been a unique thing in the group of sageuk. So I am a bit disappointed to be honest.

So Overally, the drama is not bad rather I would say it's moderately average for which I give 7/10 hence indicating that it's worth giving a one time watch. I feel they dragged the ending to some extent for which many things became repetitive but in the end they had rush IDK why. They had the potential to do better but so be it since it's a over anyways. I started it because of the high ratings that I saw in articles saying it is MBN's highest rated Kdrama in their 10 years of history. Historical dramas getting immense recognition from Knetz is actually a big deal and It indeed is the best among all the MBN dramas tbh but it could have been better. You should try watching first 6-7 episodes and decide for yourself actually.

P. S. I will simp for the first half of the show.
