We live in an age of Hollywood mega-franchises. Everywhere you look, there are new movie franchises being developed that are meant to make lots of money and produce tons of sequels. There are plenty of franchises that have done just that. There are others, though, that never totally got off the ground. Instead, these franchises squandered their potential before they were even completed.
Usually, a planned franchise fails to be completed for only a couple of different reasons. One reason is a lack of box office enthusiasm. If the first movie didn't make money, there's no reason to think the sequels will. Another potential reason to cancel a franchise is a lack of enthusiasm from critics. Often, these two things go hand in hand, and franchises are canceled before they even spread their wings.
