Most sequels are made merely for the money. Now if you like the brand, that's great. But if you think about it, half of these films are completely unnecessary. In some cases, films have been wrapped up in such a tight bow that tearing it apart for the sake of a sequel leaves you with a horrible mess and wrapping paper all over the carpet. Perhaps the biggest offence is that some of these films leave no space open for a sequel at all. By prying open a film for the sake of a sequel, you're often left with a bad taste in your mouth. Sequels in this instance are almost never received well, therefore they seem more detrimental rather than beneficial to their brand. At the end of the day, they're pointless, and the world would be a better place without them.
5. Monsters University
Ok this one is technically a prequel but the principals for why it was made relate to the sequel problem. Monsters Inc. was wrapped up with a neat bow. The characters had made up, the villain had been thwarted and the little girl was even brought back in the end for a reunion. Yay. Now, there was room for a sequel, admittedly small room though. We could've seen how Monsters Inc. worked as a laugh factory, as opposed to a scare one. But that would've been a stretch, and probably incredibly repetitive. Therefore, the writers decided to make a prequel, which is always a cause for concern, being that prequels are indulgent and largely created in order to milk a brand for as much money as possible. With Monsters University, as you can tell by the title, the film will focus on the monsters at university. Judging by the trailers, the focus will be Mike and Sullys relationship, in that Mike is the geek and Sully is the jock, and they eventually befriend each other. But that's not the issue. The issue is that theyve tried to introduce some emotional stakes, that Mike could be evicted from the university. The problem with a prequel is that it must follow a specific logic. Mike must graduate from the university, in order for the events in the first film to make any sense. The writers will manipulate us into thinking he won't, but at the end of the day, we all know he will. It's pointless to even bother trying to convince us otherwise.
