Baian the Assassin is a very good show.
I say "show" because it is exactly that, it's a DVD of two episodes of a 90's Japanese TV show, rather long episodes at an hour and a half each... Featuring some VERY good acting, the likes of which most westerners will never see on their networks again, unfortunately.
Veteran Actor Ken Watanabe is wonderful as always (he always delivers in the many Jp films I have seen with him in it) in the role as a compassionate Doctor with a secret side, that of an assassin.
I am rather amused to a point (the point, where as a fan, it begins to IRRITATE me) to see reviews talking about this as a "movie" when it is, in fact, NOT a movie. A minimum of googling would reveal this! It is, however, a fine example of what I believe is called 'Jidai Geki' (from the Wiki: Jidaigeki (時代劇) is a genre of film and television or theater play in Japan. The name means period drama, and the period is usually the Edo period of Japanese history which was from 1600 to 1868.) meaning that if you enjoy character and plot exposition as much or more than THE ACTION then you might want to give these a try. I am anxiously awaiting the next releases of these on DVD now.
I am by no means an expert, but geez - It's awfully boring, and even worse: MIDLEADING - to read a review in which an opinion is given where the reviewer in question is ignorant of a whole genre, you know?
So, to reiterate: It's a DVD of two episodes of a Japanese TV show...and hopefully this release, along with the Zatoichi TV series DVD releases, bodes well for the fan of Jp TV of the past... It's a veritable goldmine!
