Well what I like about the presentation of Hikaru no Go is the last part of the episode where there is a host teaching you how to play Go. This was very educational and so each episode teaches a move or a principle which was watched during Hikaru no Go. So for example in one episode, Shindou does a cool move in Go. At the end of the episode, the host teaches the move that Shindou done previously during the episode. This, I found very interesting.
Now the enjoyable parts of Hikaru no Go is the actually playing of Go. Each time two people verus in Go during the episode, it just gets too intense and very exciting. It will make you not leave your seat. Each move is fully emphasised by the music and the visual. It is just that good.
And finally, its originality is kept in place.
