Once upon a time... consumer goods were built to last. Then, in the 1920’s, a group of businessmen realized that the longer their product lasted, the less money they made, thus Planned Obsolescence was born, and manufacturers have been engineering products to fail ever since. Combining investigative research and rare archive footage with analysis by those working on ways to save both the economy and the environment, this documentary charts the creation of ‘engineering to fail’, its rise to prominence and its recent fall from grace.
The Light Bulb Conspiracy is a tightly argued documentary with a genuinely compelling central thesis — planned obsolescence as a systemic corporate strategy — backed by solid investigative research and rare archival footage. The plot structure is its strongest asset, tracing the phenomenon from the Phoebus cartel of the 1920s through modern printer cartridges and electronics with clarity and momentum, earning a 4. Cinematography is functional but unremarkable for the genre, relying heavily on talking heads and stock footage without distinctive visual storytelling, landing at 2. Acting (interviewee quality and on-screen presence) is similarly mixed — some compelling experts but no standout voices that elevate the material beyond standard documentary fare, sitting at 2. Novelty is moderate: the planned obsolescence concept was not entirely unexplored at the time, but this film synthesized it more accessibly and compellingly than prior efforts, earning a 3. The ending gestures toward grassroots solutions and repair culture optimistically but doesn't land with particular force or surprise, a solid 3.
