As an avid lover of manga, Hikaru No Go was one of the classic of is time and this adaptation is really good is in own way and bad in others.

The story is mostly the same which make it a nice story about a young boy with his mentor who grow up with the game of Go.
They add some parts here and there like a little love story and a cool bit with monks. The relationship between son and mother in this drama is also way better than in the manga which make it more relatable.

Where it start to go wrong for me is the change of mentality for the main character who is a pigheaded brat in this drama. The game of Go is presented as noble but many of the players in this drama play it like any chinese P2W game. It make it somewhat more realistic in their actions but it devalued the characters who where supposed to be more composed.

So take this drama as it is, a more dramatic adaptation which make this story sometime funnier and make you upset some other time.
