Film series are created when a film becomes a success. Sequels, prequels and spinoffs can turn a group of films into a real Cash-Cow Franchise. Sometimes the makers choose not to make another movie based on the success of the first one. This can be due to lack of interest or the knowledge that they will not be able to duplicate everything the original made great.
Many others simply go for the quick buck and mass produce new movies. Though a huge flop or critically panned film can halt the sequel frenzy, there have been cases when sequels continue to be made long after audiences and critics gave up.
