Film franchises are unique in that they grow with us. We become invested in the characters and story lines and follow them like our favourite TV shows over a period. We sometimes wait up to 5 years to get all the parts of the story but occasionally that wait can be up to 20yrs! In that way they grow with us, characters get older and the content gets more complex or mature. Not all parts of these franchises are necessarily great, but they form part of a bigger picture, a story we are heavily invested in and must know what happens next!
