Mizuu uses two free and open websites to get data about movies and TV shows.
Both sites are open and allow any one to add and edit the content. This allows for extremely quick updates, and allows you to contribute, if you find something missing.
The best way to check if Mizuu will support your movie or TV show collection, is to check out these two sites and search for the content. With more than 30,000 TV shows (and details about almost a million episodes) as well as more than 75,000 movies, odds are that most of your collection will be covered.
Mizuu wouldn’t have been possible without these two sites, and I really encourage everyone to help and support the sites.
