I don't agree. The McGuffin (the decryptor chip) is magic, the ethical conundrums are juvenile. It's teenage wish fulfilment for liberal geeks (and I say that as a liberal geek); a high-tech version of the Blues Brothers and just about every gang-of-mistfits-thwart-horrible-landlord film.
Sorry, but I saw it in the theater when it came out and it was just a total let-down - not my idea of a serious film at all.
