Back to the Future mistakes.
Sorry if this has already been done, but I've searched the forum and haven't been able to find anything on this, so I thought I'd start a new thread on it anyway.
I don't think I need to explain what this thread is about, as the title alone should say enough, but for all you BTTF fans such as myself out there, what mistakes did you notice were made in each film? What confused you?
Here are a few things I don't understand:
BTTF 1: Basically, when Marty goes back in time to 1955 and accidently bumps into his parents; causing his own mother to have the hots for him and not meet up with his dad, he prevents his own birth, therefore unless he gets his parents back together in just a matter of time he will 'erase from existence'. Hence why his siblings started gradually disappearing from his family photo. However, the Marty who carries the photo comes from a divergent timeline in which his entire family exists; he was born, he has his own life history and existence. So for as long as he exists these things will. Even if our divergent timeline approach is not the truth, a logical consideration of the matter will quickly dispense with any notion of these "symptoms" of the temporal anomaly being possible. Although it has not yet been determined whether his parents will get back together or not; he is in theory vanishing because his parents have not gotten together in the future which is his past. Because he is attempting to restore his families past there is still a chance they'll get married. He more or less real based on the likelihood of his birth, so it is not a percent of probability. Were that the case, he would become non corporeal, ghostly, and lose the ability to affect reality at all. At the moment he arrives in the past, he either is real or is not real, and he remains in that state until he either leaves the past or dies there. Which is why the vanishing picture thing made no sense to me, as it either exists or doesn't exist. How could the theoretical other picture even exist? No version of Marty McFly would be carrying a picture of that place with no one in it; nor would the picture make any sense if he were standing on one end, alone in the picture. And a picture of Marty's brother without his head is far more absurd! No, this Marty has a picture, and the picture does not change. Nor does he: he is who he is. He may have no future, but he has a past in an alternate timeline.
BTTF 2: Pretty simple this one, as the only one I can think of now is the fact that Marty and Jennifer went ahead to 2015 to see their own future. The future in which they have their own children and so on. But in reality, if they had both skipped ahead from 1985 to 2015 via the time machine, they wouldn't have been in their home town between that period of time, therefore they wouldn't have grown up to raise a family. So how could they possibly have gone 30 years into their own future to see themselves as a couple of middle-aged parents?
BTTF 3: In the photo Marty takes of the gravestone which shows Doc's death, it says "Missed by his beloved Clara". But Clara died in the ravine, hence it's name "Clayton Ravine". When Marty went back, Doc saved Clara, preventing her death. Therefore, in 1955, before Marty went back to 1885, Doc wouldn't have saved her, leaving her for dead, so how could she be Docs "beloved Clara?"
Meanwhile, if doc couldn't repair the DeLorean after it was struck by lightning and had to leave plans on how to fix the time circuits using 1955 componants, how did he build the time circuits for his train?
So, let me hear your queries. 😉
