Hoverboards, flying cars, the future isn't quite like we imagined it would be back in 1989 when Back to the Future II came out. Don't let that bring you down though. Christopher Lloyd reprised the Dr. Emmet Brown character to give a gentle reminder about the meaning of Back to the Future.

Side note: a friend made me sad and feel old at the same time. In a couple of days the entirety of the Back to the Future movies will all be about past time periods.
