Wow, this is an amazing sequel to the first film, with heaps of iconic moments and a great plot. The first part of the movie begins right where Back to the Future left off, and Marty, the Doc and Jennifer head off thirty years into the future to 2015. The mystery of something happening to Marty's kids become clear. We get to see an interpretation of 2015, which while inaccurate now, is actually still pretty cool, it isn't too futuristic in its vision, keeping just enough familiar sights to be plausible. The events that happen in 2015 really just sets up the rest of the film, due to a massive time paradox caused which forces Marty and the Doc to return back to the past. There, it follows an exciting mission, where the stakes are high. The movie keeps you highly engaged, the humor and charm that made the original great is not lost. The only slight negative is that the ending leaves a sequel confirmed, which means limited closure.
