Modern society is cold and impersonal, and has made humanity insensate and boring. This is the assertion of three guys in “Primitive Technology,” who run around the city destroying cell phones and laptops while creating inventions out of garbage. Things go according to plan until the introduction of a new member, whose invention is so awesome it causes jealousy and threatens to break the group up. Fast paced and lacking the heavy handedness often associated with Luddite-themed works, “Primitive Technology” is a winning effort.
