Popcornflix is a free streaming movie site that plays documentaries, Hollywood films, and other content. Users are asked to enter their birthday to prove they're 18 before watching R-rated movies, but age isn't verified in any way. Aside from a movie's ratings, descriptions don't list any information about nudity, violence, substance use, or other adult content, and there's quite a lot of this content to be found in varying amounts based on the movie itself. The site also features ads on the home page, as well as before and during some films.
CuriosityStream is an educational video site that hosts documentaries and other learning-based clips on numerous subjects.
