Some movies leave fans hungry for more, with films like "The Godfather," "Star Wars," "Lethal Weapon" and "The Bourne Identity" being ideal for sequelization. Filmic follow-ups can build on the original narrative, tell another side of the story, or just deliver more laughs, chills and thrills with your favorite characters. Many times, however, sequels just try to squeeze a few more bucks out of the initial audience, even if the product's sell-by date has already expired, the original stars don't want to return or the first film just didn't seem to warrant another chapter. Hollywood has a depressingly long track record of truly unnecessary sequels.
