Back to the Future part2

Rating: 10/10 (26 April 2006)

This movie is an great nostalgic masterpiece for every nation or age. I'll give an 10/10 for all three pictures... "Plot holes: In the future, old Biff steals the time machine to travel back to 1955 and give his younger self the almanac. When he returns to the future (and crashes into the trash cans) it is the same future as he had left even though it should have been an alternate future in which he was rich".
But in my opinion, the old Biff on his way back to the normal future, should disappear at all, because changing future of young Biff he is changing his own life (and the future environment) the old Biff is not part of it anymore. And he's personal experiences have never happened, so his development stops at the same moment when the young Biff even touched the magazine. The new future belongs now to the young Biff who got the Sport magazine. So the DeLorean should stay in 1955 or flew (if he disappear on it's way) empty to the bad future.
Plot hole: If you take all three pictures and put them together that you'll realize that we see maybe 2 week's of the life of Marty McFly. In the beginning he is an shy virgin, which is waiting for his first shot, in all period (of three movies) he has no chance to start his sexual experience. But in the film his character changing very quick in an experienced macho. It is impossible for any person to change in a week or two so fast. Even if the life events are going very fast, the mind of the person needs time to put it all together. My point is that this movie was made 1985, 1989 and 1990. Time gap of 5 years, during making the movie M.J. Fox grew up and changed the personage into a brave macho guy. So the story period is to short to make such change, M.J.Fox needed 5 years and Marty McFly only a 2 week's.
Same impossible change you can see in The Lords of The Rings. Periode of the story is only a week top. But in the beginning Frodo is afraid to even touch the sword and the following movies he's cutting demos like butter. Can't be wright, you can't make a man in couple of hours from a fuz... But please find out for your self and make your own judgment
