A claim has been made that only 10 movies from a particular decade are truly perfect from start to finish, but there is uncertainty about which decade is being referred to, with some outlets suggesting it is the 80s and another suggesting it is the 90s. The discussion appears to be related to nostalgic and family-friendly movies. Various outlets are also highlighting notable movies from the 80s, 90s, and other decades, but it is unclear how these are connected to the initial claim.
