existenz combine director david cronenberg traditional love of blood and gore and explode head with the more confusing aspect of a reality twist david lynch film . and it actually work effectively . i would not bother try to give even the bare bone of a plot synopsis here because it will only cause more confusion . all you need to know be that the film be about a virtual reality computer game that be so incredibly lifelike that it become difficult to tell the difference between reality and virtual reality . the film almost seem to abandon it technology fear point at the end and but then it throw in the final twist in the very last line of dialogue . there also some very gross sexual imagery base around the bio port in the protagonist back and as well a some very gross act from jude law . he manage to come off a naive and stupid and boring and any other annoy habit you can care to think of . jason jennifer leigh come off much good and and everyone else can be call a supporting character and include willem dafoe in a functional and if unspectacular and role a a money craze mechanic . overall and existenz be a very effective sci fi film about the possibility technology can present and the possible consequence it will receive .
