THE LAST REVENGE (2011) is a solid feature-length TV drama starring the always reliable Tatsuya Fujiwara. He was the main draw for me here having been a fan of his since I first watched 'Battle Royale' but the cast around him bring depth to their roles and the overall production is quality.
I wish TV movies were of this kind of class in the UK and US - they used to have something about them but not much so lately.
This Japanese period film is certainly one to seek out.
