Back to the Future Part II1989

For reasons unknown I had not watched the sequels and finally today watched this. Beautifully complex compared to plot heavy first part and more fun sci-fi elements that I love. Concept of time travel in this was way ahead of its time - it mentioned about time paradox, alternate reality, temporal event sequence etc etc. Seriously I will never get bored of these films. Robert had crafted way too addictive Sci-fi world. One of the most PRECIOUS time travel worlds ever created in the history of cinema.
