How many of those reading this article remember or heard about Back to the Future coming out in theaters on July 3, 1985? It has now been 40 years since its success the movie made in the box office which made over $388 million.
Critics have considered the film as one of the most successful movies in the science fiction genre and among the best films ever made, during its time. Actors Michael J. Fox and Christopher Lloyd gave stellar performances in their roles as Marty McFly and Dr. Emmett Brown as characters go back in time to explore the past and see the changes in the future.
The story line kept in line with logic that is based on the meaning of time travel and how changing the past alters the future. Surrealism of the film has made certain predictions of technology to come true that included video conferencing, such as FaceTime, and hoverboards as it appears in the sequel.

The connection of Back to the Future to the audience
Back to the Future opened the door to many ideas for new stories that predicted the future and time travel.
Other films that tell the story of time include Interstellar, Click, Men in Black, Hot Tub Time Machine, and many other attempt to make a form of story line of their own. None of these films live up to the same logic and story line as Back to the Future.
Robert Zemeckis and Bob Gale did a great job to give the audience an understanding how time travel works. Change one thing, change everything. The story has done a good job in explaining the logic how time travel works and understanding the past.
Like many movie franchises, the first movie of Back to the Future earns the highest praise than the two sequels. Zemeckis set the standards of storytelling where logic connects the dots for the audience to understands the story line.
The purpose of the movie is for the audience to understand the theme and the concept of the storyline. This gives would give sense of why Marty McFly goes into to the past and back to the future.

Back to the Future has built the world of sci-fi as we know it
The legacy of Back to the Future is built behind science fiction and those who took part of the film including the cast and crew. The talents of Fox and Lloyd is what kept the audience engaged especially with their personalities connecting with their characters. Under Zemeckis, the movie thrived in a perfect setting to keep the audience engaged with curiosity about time travel and how the concept works.
With the setting of the antagonist of Biff played by Thomas B. Wilson, it tells the consequence about time travel and obstacles to prevent the consequences of altering the future. Biff really challenges both Marty and Doc no just in the first film of the franchise, but throughout the next two films.
As of today, Back to the Future stands on a platform of its own that no one film could potentially match. Zemeckis had the vision of the film in the direction that he took to the promise land.
