Ars Technica's review of Alex Gibney's four-hour documentary on Elon Musk offers a mixed verdict. The film is described as provocative and compelling, yet the reviewer argues it would benefit from tighter editing. The length is a central criticism, with the piece noting that the runtime works against the film's impact.
The review also observes that the documentary feels like two different films, suggesting a tonal or structural split. For readers already familiar with Musk's public trajectory, there is little new material. The reviewer notes that Ars Technica's audience, in particular, may find the film more of a recap than a revelation.
As a single-source review, this assessment reflects one critic's perspective rather than a consensus. Still, it highlights a common tension in long-form documentary filmmaking: balancing depth with pacing, and novelty with accessibility.
