Time loop to revisit original movie creates incredible sequel

Rating: 9/10 (14 October 2013)

This picks up right from where the first one ends. Marty, Doc and Jennifer goes to the future to help save his children in 2015. Only things go completely off the tracks when Biff in the future steals the DeLorean to change the past for his benefit.
The time travel in this movie is even more complicated. It revisits the 1955 timeline actually make it work better. The scenes where he revisits the same time as the original is truly inventive. The great thing is that it combines with the original to make the whole series even better. It's seamless integration is what makes this sequel superior to any other sequels. It's a work of mathematical genius from Robert Zemeckis.
