Back to the Future is one of the greatest movie trilogies out there, but that doesn't mean it's safe from nit-picking. Without getting into any talk about the logic of time travel, here are the 8 parts that still bother me:
1. Marty missed the entire improved childhood he created for himself.
The end of the first Back to the Future movie seems like a happy ending where everything worked out and his parents and siblings are richer, better looking, more successful people. But this is actually one of the most tragic endings ever. Everyone's life is better, and theoretically Marty has this wonderful and different childhood, but he missed it. He still only remembers the sh*tty childhood he had. He doesn't actually know who these versions of his family members are. All of his memories that have formed his personal identity exist only in his mind now. But, hey, at least he got that shiny new truck.
2. Biff tries to rape Marty's mom, and then she and Marty's dad hire him to work in their home?
It must be some weird power play on George McFly's part that he wants to keep this aging, pathetic version of the man who once tried to rape his wife around to do housework for him, but even if George derives some joy from the arrangement, wouldn't it make Lorraine feel uncomfortable? And it's not even like Biff turned things around and became a good employee. He lies about how many coats of wax he's put on the car, for god's sake! It's almost like lying, bully rapists aren't good people.
3. Don't George and Lorraine McFly find it insane that their son looks exactly like the stranger who got them together in high school?
Yes, 30 years had passed, but Calvin "Marty" Klein was integral, not only to getting George and Lorraine together, but to making George into a confident, functional human, instead of a bumbling nerd. You'd think that kind of importance would earn some facial recognition. If I asked you to picture a character from a TV show that was on 20 years ago, you could probably do it. George and Lorraine should be freaked out.
4. Why does a hoverboard "not working on water" mean that it can't move, but it still hovers?
The ability to move isn't really what makes the hoverboard special. It's, you know, the hovering part. I don't know what the fake physics is that made hoverboards possible in this fake future, but it seems logical that if hoverboards can't run on water, the first part to stop working would be the hovering.
