What begins as a paranoid gloss on David Lynch's "Eraserhead" (the central character is an antisocial loner in a fittingly creepy apartment complex) eventually unravels and stalls due to its own hyper-allegoric art-house pretensions. But for a while, it's an engrossing, unconventionally entertaining tale of a computer programmer (Jeremy Sisto) who receives empty packages inside his apartment...even after he changes the locks. While it's clearly a work of science fiction, the conceptualization of "the future" is presented in a minimalist mannersave for some complex-looking computer screens and virtual-reality scenesthat envelops the cerebral thriller elements quite nicely. In addition to "Eraserhead", it also bears some resemblance to David Cronenberg's more playful "eXistenZ," with a similar emphasis on the blurred line between hallucination and reality (metaphors abound), but the double- and triple-crosses the plot lays out eventually become tiresome.
