There's a big problem regarding the confirmation of Frozen 3. The Disney franchise began in 2013 with the release of the first film. It was an immediate hit among all ages making a sequel inevitable. It was once rare for Disney animated films to see successful sequels, with most Disney Princess movies getting straight to video follow-ups to their stories. However, Frozen brought Disney success it hadn't seen in years. The film was mainly praised for avoiding the outdated princess tropes and overdone love stories. Instead, Frozen focuses on the dynamic between Elsa and Anna as sisters, which was refreshing in the new era of Disney.
