The very notion of a "movie franchise" speaks volumes: in essence, a movie franchise exists to convince audiences to spend as much cash on a single product as possible. And once you have somebody hooked into an idea, concept or character, chances are that you can probably exploit them for at least a couple of years, selling fans the same premise for as long as possible, until finally - exhausted and disillusioned - they fall by the wayside, spluttering the words: "No, that really is last time I see a Transformers movie!"

Sometimes a franchise will garner a reputation based on what it didn't do, whilst overlooking its successes.
