xDocumentaries aims to be your guide through the hundreds of documentaries freely available online. We rank them by relevant ratings, so you can quickly discover and watch the better ones. Quality is important to us, so we'll remove videos that get broken, unlike other websites. What you see here is a work in progress, but you can already jump in, browse our current list, and watch some great films. Enjoy!
