This Reddit Thread on “Fan Theories” is Crazy and Cool
The whole thread is here, but allow me to cherry pick my favorites (click the links provided to read more detailed descriptions):
The Empire in Star Wars were not actually the bad guys in so many words; they were actually preparing for a future war that the Republic (the good guys) were never organized enough to handle on their own. Emperor Palpatine simply pulled the entire government system up by the roots, and completely reconstructed it in order to be ready for the Yuuzhan Vong invasion. While the Death Star was an Empire creation, it was Grand Moff Tarkin that wanted to use it as a tool of fear against the rebel alliance; but it never really made much sense to use it as a weapon against the scattered rebellion - but it would have proved very useful against the Yuuzhan Vong.

By all accounts, Skynet in the Terminator movies should be able to easily wipe out humanity almost overnight with chemical weapons - vastly deadly chemical and germ warfare systems have been around since before the 1950’s, so it’s not exactly an impossibly futuristic concept. What prevents Skynet from doing this is the fact that she (?), like her human creators, is sentient being who thrives on interaction. Skynet intentionally prolongs the war for an eternity because war is the only way she knows how to interact with humanity. Without humans around, she would be forever alone - the worst form of mental torture. Any mistake she makes are to simply ensure that the humans never stop fighting her. [Link]
Doc Brown in Back to the Future was actually suicidal by the time he built the DeLorean time machine and was determined to kill both himself and Marty if it did not work. He spent his entire family fortune through decades of failed inventions and was likely bankrupt by the time he finished the DeLorean. When the (basically untested!) time machine accelerates to nearly 100mph, he stands directly in its path and forces Marty to remain by his side… yet both of them look equally shocked when the car vanishes before their very eyes. Despite his eventual elation at his successful experiment, that was not an outcome he expected. [Link]
All of Quentin Tarantino’s movies take place in the same universe - a universe where cinema, pop culture, and ultra-violence are glorified thanks in part to the events that take place at the end of Inglorious Basterds. That is why all of the characters in Tarantino’s movies seem to have encyclopedic knowledge of obscure cult cinema - because that kind of stuff has become deeply ingrained as part of American Culture after the end of WW2.

Neo in The Matrix is actually part of an experimental program called the “Human Interface Project” created by the machines to genetically engineer human super batteries that were physically incapable of ever leaving the Matrix. But, rogue programs within the Matrix had a hidden agenda attached to HIP subjects that were intended to allow machines to inhabit flesh and blood physical bodies. Neo was a side effect of both of these experimental goals, allowing him to manipulate the Matrix regardless of whether or not he was plugged in or not. He was like a walking wireless hotspot with network administration privileges. This is also why Agent Smith is able to leave the Matrix in the sequels - Neo corrupted his data, and accidentally passed on some of his network administration privileges. [Link]
In the Harry Potter movies, Voldemort doesn’t have any hair as a means to prevent anyone from making polyjuice potion to impersonate him. [Link]
Of course, the classic Disney’s Aladdin theory also comes up: Genie makes numerous references to present-day pop culture and mentions being stuck in his magic lamp for 10,000 years - making the setting of the film at least 10,300 AD. It is so far in the future that the name “Arabia” has been corrupted in to “Agrabah”. The Magic Carpet is actually a technological relic of an era long destroyed by some unnamed apocalypse, and Iago is a descendant of genetic cloning to make animals intelligent enough for speech.

I’m actually shocked I didn’t see anyone mention Squall Is Dead, either, which posits that the main character of Final Fantasy VIII is killed at the end of the first disc and the entire rest of the game is spent watching Squall’s brain die, which causes logic to break down on a fundamental level. Certainly would explain the numerous sharp left turns that game takes in its narrative.
