WHY UNDERSTANDING DOCUMENTARY TYPES MATTERS

Documentaries are more than educational tools — they are cinematic experiences that captivate, challenge, and inspire. On platforms like Netflix, documentaries have become a cultural phenomenon, offering a variety of storytelling approaches that span across genres and subjects.

To truly appreciate this form of storytelling, it's essential to understand the different types of documentaries. Netflix’s vast catalogue can be categorized by theme, tone, and narrative style. In this guide, we explore four dominant categories: History, Crime, Science, and Nature, each with a powerful film example that defines the genre.
