Fan fiction is what literature might look like if it were reinvented from scratch after a nuclear apocalypse by a band of brilliant pop-culture junkies trapped in a sealed bunker. They don't do it for money. That's not what it's about. The writers write it and put it up online just for the satisfaction. They're fans, but they're not silent, couchbound consumers of media. The culture talks to them, and they talk back to the culture in its own language.

Cinephiles love reading way too much into a films, and 99 percent of the stuff they come up with is bullshit ("what if Haley Joel Osment was also a ghost?") but other times, they turn out to be right (yes, Harrison Ford really was a replicant in Blade Runner).

Well here are some oddball, yet strangely plausible, alternate fan theories that in many cases actually improve the movie quite a bit.
