Observational documentaries are films that appear to capture events in real time without interfering, using techniques like handheld cameras, diegetic sound, and long shots without voiceovers or interviews. They aim to create an intimate connection with audiences by passively witnessing real events unfold. An example is Keeping Up with the Kardashians, where camera crews follow the family's daily lives and capture their unscripted conversations, though the scenarios may be staged for entertainment.
