One of the primary concerns surrounding "Cannibal Holocaust" is its use of found footage, a technique that was relatively new at the time of the film's release. The movie's handheld camera work and raw, unflinching portrayal of violence create a sense of realism that has been both praised and criticized. While some argue that the film's use of found footage adds to its documentary-like feel, others claim that it desensitizes the audience to the graphic content.
