Back to the Future 4 will never happen, according to Robert Zemeckis. While this is undoubtedly fantastic news, there are several things that a sequel may have accomplished. While there have been requests for a sequel to the Back to the Future trilogy, which was released between 1985 and 1990, many fans are happy with the current version. Because of this, Back to the Future stands out as an uncommon example of a franchise ending while it was still successful and maintaining its legacy.

While Ghostbusters, Blade Runner, Top Gun and many more 1980s classics have received legacy sequels in recent years, Back to the Future is one franchise that seems untouchable. Legacy sequels and reboots have been hit-and-miss, so it may be for the best that Back to the Future remains in the past. Still, this means that all the untapped potential of a Back to the Future sequel will never be realized, and there are a few things that fans of Doc and Marty would have wanted to see.
