Genya (2010)

Unusual

It is absolutely captivating! It has xcellent written story, stellar acting, perfectly matching music.
It is not at all a standard Japanese drama, at least I have never seen something similar among them until now.
Be aware, it is very creepy and emotionally hard, very revolting and in every respect surprising.
Even if it was a hard one, I must say that it deserves 100% its time watching.
