When George Lucas envisioned a world of good and evil where glowing sticks yielded deadly results, most of the world wasn’t on the same page. Nevertheless, Lucas wrote nine original screenplays called the Star Wars saga. After releasing six films under the title, however, Lucas stopped producing the Star Wars films, leaving three screenplays untouched—until now.

The return of the Jedi stands among many other returns, such as hobbits, Neverland, lions, witches, wardrobes, and fourth and fifth sequels to children’s movies. Most directors and producers base the decision to create a sequel on the popularity of the original, but most of the time, sequels fail to live up to fans’ expectations. In those cases, sequels are better off never made.

Producing a sequel generally brings in more money than the previous film, but only to an extent. For instance, of all the “Shrek” films, “Shrek 2” has the highest gross box office earnings, nearly doubling the intake of the first Shrek film. “Puss in Boots,” the fifth movie in the franchise, is also fifth place in box office earnings, earning just over half that of the original film. People tend to come back for seconds, but they are far less likely to come back for fifths.

Another pattern of sequels is a change in the cast. For example, in Christopher Nolan’s “Batman Begins,” the lead female character is played by Katie Holmes. In the sequel, “The Dark Knight,” the character is played by Maggie Gyllenhall. Fans of the franchise who generally enjoy connecting to a certain image of a character had to change their view of the character to fit the new actress. Casting changes often break connections between movies and their sequels.

The greatest challenge of producing a sequel, however, does not lie in any of the logistical aspects. Moviegoers watch Luke Skywalker, Frodo Baggins, Lucy Pevensie and Buzz Lightyear beat the bad guys and save the world, and it brings comfort and contentment when at last  the winner is proclaimed. After hours or in some cases years of suspense,  good conquers evil and all is resolved. Creating a sequel for the sake of money and popularity destroys the relief of resolution.

The Star Wars additions may turn out incredible with appearances from Mark Hamill and Harrison Ford, state-of-the-art special effects, and the  screenwriting of George Lucas. Most Star Wars fans, anxious as they may be, would prefer a job well done. However, if the film fails to live up to its predecessors, it only proves that stories with the ability to truly impact and define people often affect people similarly to love at first sight. The best stories only need to be told once.
