the poor dvd video quality be the only reason why i give this movie a 9 instead of a 10. that could have be so much good and this movie deserve it . this be truly a movie that cover several theme simultaneously . if you do not like movie about serial killer and but be fascinate by the astonishing bureaucratic culture in the former sovjet union and this movie be a must see anyway . i can not compare it to silence of the lamb for several reason . the way the serial killer be portray and have be do far much well in citizen x. you see several detail of his private life and because you travel along with the killer and which give you some idea of the source of his constant anger and sexual frustration . the only other movie i have see that be as realistic a this one be henry portrait of a serial killer . if you be fascinate by that movie you definitely need to take a look at citizen x .
