I watched it yesterday. It was actually a good drama. The Go Master series is more comedy (I have watched two of them). Despite a bit slapstick comedy, they are still okay.
The movie about Go Seigen is also available on YouTube. Unfortunately without English subtitles although there is not so much speaking in that movie: 2006年 《吴清源》 昭和棋圣 张震主演 720P 超清 - YouTube
