Here is a topic for your show, Sequels that do not need to exist, like ones that continue a closed story. I have a lot to say on this topic, for example, The Omen IV, The Omen III ended with the second coming, there shouldn't have been a fourth entry. Or even the Halloween sequels after II (involving Michael Meyers), but its unfair to pick on slasher sequels for being unnecessary.
What say you?
