"This list looks at a particular type of sequel, the one that has to follow a famous or respected movie, and that is not only bad compared to the original, but so ill-advised or unnecessary that it becomes an insult to the film.
The reason behind this is usually the desire to capitalize on the success of the first film, with little interest to the artistic value of the original. Other times, the sequel comes from an attempt at making a sequel as great as the first one, and in this case, the good intentions of the filmmakers can be justified, but their results certainly cannot."
