What a wonderful movie. All of the mind twisting about just what is reality anyway? and a feeling for what it's like if you are a videogame character living in a videogame world, where you may have to chop off a person's head to proceed with the game. I love the homage to Philip K. Dick, who beat the reality problem nearly to death in his works (movies made from his stories include Blade Runner, Total Recall, Minority Report, Screamers, Imposter (which I haven't seen), and the embarrassing Paycheck). When the main characters in eXistenZ get hamburgers to take to the motel, the burgers come from Perky Pat's, and Perky Pat comes from Philip K. Dick. Residents of Mars, to spice up their boring lives in The Three Stigmata of Palmer Eldritch, take a drug and play with their Perky Pat dolls, becoming the dolls and trying to live a Barbie and Ken existence. They know it's not real, but it becomes more real than real. You know that you are viewing a great simulation of reality in this movie when the burgers come from Perky Pat's. This movie would not have been made if Philip K. Dick had not lived, and we are better for both of those events.
It also seems to me that people who love The Matrix as much as I do - and there are millions of us - can't help but love this film. I can only attribute this movie's small potatoes performance vis a vis The Matrix to not enough people having seen it. So if one one-hundredth of you Matrix fans out there and all of the Matrix haters one reviewer referred to would rush out and buy this DVD you would make David Cronenberg really rich, as well as one of our finest creators of off-kilter movies.
