'Invasion' fits within the documentary genre, focusing on real-life events and historical analysis. Typical elements of documentaries such as archival footage, interviews, and a narrative exploring social and political themes are present. What makes 'Invasion' stand out is its deep exploration of collective memory and identity, using the 1989 U.S. invasion of Panama not just to recount historical facts, but to examine how societies remember, reinterpret, and sometimes forget their past to shape their current identity. This introspective approach adds a psychological and cultural dimension that elevates it beyond a conventional historical documentary.
