to simply tag ganja and hess with a label of blaxploitation would be a serious understatement and a this be probably the most ambitious black film of entire 70 decade . the substance of the film cover horror and but you really wouldn not say so and a there no explicit violence or bloodshed on screen and and the whole production relies on it dark and moody atmosphere . it a really weird and ultra slow film and definitely not suitable view in case you be look for barbaric 70 horror . i can not say i like it very much because and honestly and it a super pretentious film that go on for far too long without actually handle about anything . i appreciate smart dialog and subtle atmosphere as much a the next guy and but a synopsis claim to revolve on blood addiction and passionate murder eventually must show something and right . duane jones ( night of the living dead ) give a marvelously languid performance a a doctor who suffer from an insatiable desire for human blood and bring onto him after be stab with an ancient curse dagger . shortly after and when his assistant ( play by bill gunn and the director ) commit suicide and dr. hess come into contact with his widow ganja and sweep her along in his strange and depress vampire universe . the acting performance and film location form a potent mix and but the pace of the film be truly soporific . bill gunn artsy attempt to disguise the lack of budget with various ingenious camera angle and sound effect and but he still can not hide the fact there no suspense or involvement in the screenplay . perhaps the heavily cut version blood couple be more endurable . i can only imagine some of the dialog be cut in that version and a there no gore or sleaze to censor . it an interesting film consider it historical background and but it doesn not hold any entertainment value .
