i watch this film not know anything about it . i have presume it be a sci fi b movie of some sort . how wrong i be . the plot be enthral and intelligent and the cast be all charismatic and the whole film just make you think for a change . some of the riddle stump me completely but in the end the answer be rather simple . i be quite baffle at the low scoring of this film a i think it be quite unusual . if you like the film se7en ( seven ) with brad pit or the matrix then you will like this . there be no major special effect or fancy gimmickry here at all . it be all about the plot and about build the character and build an atmosphere . it be a film however than ultimately provide no answer which may irk some people but i think the end be great . i be still not sure if the film be base on an true story or not .
