Waiting a decade -- or more -- to make a sequel isn't exactly a widely practiced business model in Hollywood. Lately, the longest you have to wait is two or three years before the next installment in whatever potential or established franchise hits theaters.

In the last few of years, however, waiting a decade (or more) for a follow-up isn't such a crazy proposition. (Um, hello, "Mad Max: Fury Road.")

To celebrate the release of "My Big Fat Greek Wedding 2", one of Hollywood's longest-gestating sequels, we present the widest gaps between two movies of the same franchise, along with whether or not they were worth the wait. (Spoiler alert: A lot of them are not.)
