The audience has many ways to entertain themselves and release their stress. One of those many ways is watching films. But when the first part of the film is hugely appreciated by the audiences, the filmmakers go on and make a second part. This increases the curiosity among the fans for the film.
However, there are certain films that have entertained the audiences for such a long period of time that the audience will jump out of rejoicing if the third part of these films will be made.
So considering the global success of these films and the big fan base that these films have, we think that these films deserve the third part as well.
