Ace Railgun: "This has been happening since forever and is nothing new but it’s something which has become an issue in my anime viewing in the past year or so. Generally a story (someones intellectual property) gets a sequel for one of two reasons. The first being the writer hadn’t finished his/her story and needed a sequel to tell the rest of the story about his or her characters or world. The second reason for a sequel is simply a money grab beating a dead horse with a stick to get more money out of the fans of the original. A lot of the time a story doesn’t need a sequel especially if it reached a conclusion but there are cases where a franchise is brought back from the dead and given life once more. The problem is that this reanimated corpse is a shadow of it’s former self and can taint the original story."
