The real monster in the Back To The Future movies isn’t the bully Biff, argues Premiere’s Gene Newman. It’s Doc Brown, the lying manipulator who deals with terrorists and nearly destroys the space-time continuum. Spoilers ahead.
The post feels pretty tongue-in-cheek to me, and it’s a fun read. The majority of it (marries beneath his age, best friend is a boy, etc.) seems pretty unimportant to me, but maybe that’s because my SO is significantly younger than me and many of my friends are older and younger than me as well. 
But I still get a kick out of the whole “Doc Brown is a bastard” because he’ll bend the timeline to whatever the hell he wants it to be. As viewing audience, we root for Doc and Marty’s reality to win out as the “correct” one, but what about Biff? He gets pretty royally jacked during the whole thing.
But hey, he’s a dick, right? So screw him. He deserves it.
Well…his theory of time manipulation is completely wrong from part two, and it was Biff who proved it!!! Follow me: Biff takes almanac back to 1955, gives it to himself and arguably goes directly back to 2015. Now, as “Doctor” Brown puts it, once you change time, the original timeline is erased, meaning that when he goes back to 2015, it should be the 2015 of Hell Valley, literally stranding “Doc” and Marty in the future. Instead, he makes his way back to a world where he’s still a pump jockey.
Also, there was a post on a blog some time back about the ending of Back to the Future is going to happy for Marty or Doc in the weeks/months after the movies when the government discovers Brown’s plutonium storage and associations with Lybian terrorists.
Marty is the only one who would suffer for Doc Brown’s indiscretions, because the Doc basically vanishes from the timeline. Flitting about the timestream with his newly created family aboard the Jules Verne-like flying timelocomotive. Marty is the one left behind to clean up the mess he made, not cool…
As long as he stays in the past… the moment he shows up in the future after McFly tells the fed about the flying train, Doc will be disappeared.
Or Marty will be institutionalized after telling them such a fantastic tale!
He still has the 1885 picture and the remains in the cave.
what the hell, Marty. what the hell.
Doc Brown wasn’t even a real Scientist.
Every Scientist knows its Gigawatt not Jigawatt…
carry on…
I would still like to know how a cool high school kid who loves rock and roll, trucks, and girls becomes friends with an eccentric, crackpot, brilliant inventor. Did they meet at a concert? A monster truck rally?
Maybe Marty answered an ad for “dogsitter, clockwinder, good with crazed scientists”
To quoteth El Biffster of the Butthead Clan: Helloooo, anybody in there? Think McFly! Think!
Emmet Brown found HIM! Some teenager in 1955 tells him he’s from the future and shows him a Working Time Machine. Said teenager also warns him of his own demise 30 years later. Knowing that if he doesn’t become friends with McFly that the kid won’t go back in time to warn him, he not only creates a paradox and destroys the world but HE DIES TOO!!! Why do you think he built that Godzilla Amp shown at the beginning?
How many time machines have YOU built? 
Not all inventors are accredited scientists.
Yes, and all elephants have tails while not all animals with tails are elephants. Point taken.
I don’t know how well that meshes with the alternate realities theorem that was put forward in 2, but on the surface it makes enough sense that I’ll take it.
I’ll leave it at that with a quote of exceeding wisdom from a brilliant mind:
“Ohh, a lesson in not changing history from Mr. I’m My Own Grandfather!”
Touche, Jarathen! Touche!
The question is not how many time machines I have built, the question is how many time machines will I build in the past when I go back there.
Starbuccaneer, I hate to be a stickler for details but wouldn’t the time of the creation of your time machines be moot as you would be able to access all time at any time? Besides, as Brown found out, getting parts can be a hinderence if the parts haven’t been developed yet. Of course you could utilize time like Bill and Ted to get parts.
