The Back To The Future movies are a flawless trilogy, and the greatest movie in the series is Back To The Future Part II. Its wonderfully optimistic portrayal of the then-future year of 2015 is utterly charming, even if audiences are still waiting for hoverboards and flying cars to become a reality. Fans have recently been celebrating the date that Marty McFly traveled to in 2015, October 21st, by sharing their favorite predictions that have since come true.
