Hello @Ri meh, welcome to the Amazon Forum! I am sorry that "Supernatural" isn't currently available from Prime Video. Video availability depends on our agreements with content owners. We're constantly working to improve our agreements so we can offer the largest selection of movies and TV shows possible.
