your favorite fan theory to explain for a fictional universe?

I like that one. I hadn’t seen it before, but it makes sense.

Grant Morrison, in his incredible extended run in the Batman comics, presented the goofy Silver Age Batman stories as Bruce’s unreliable viewpoint while under the lingering influence of repeated exposure to Joker toxin, fear gas, Poison Ivy’s concoctions and many other factors.

I can believe it; and my theory may be derivative, but I come by it honestly; I came up with it all on my own (apparently, alongside a few million other people) driving home from the theater after originally seeing The Matrix.
I guess Obvious Plot is obvious.

Actually we do have a clue, in that when the Master chose an alias in an English village {in The Daemons}, he chose “Reverend Magister”, which implies that in whatever language he uses, his title will be the equivalent of the Gallifreyan for Master or Teacher.

Bumping this one up because I heard a good one on Reddit today.

In Men In Black, when J is testing to become an Agent, he goes up against a bunch of military guys. The theory is that those guys were never in consideration for the job, it’s just part of the test to see how he reacts to being around a bunch of government people and not being in the know. Notice how they all seem to know exactly what to do (like that the tests are under the chairs), and he has no idea. They all got extra instructions before the test began, which is why J was late.

You and me both. I think in retrospect, the Wachowskis planted too many clues in the movie.

One thing that annoys the heck out of me. Back in the eighties, when The Watchmen was being released in monthly issues, I remember I had a theory about how it was all going to turn out. As I recall, my theory tied together a bunch of different elements in the series. But when the final issues came out, the actual ending was quite different than the theory I had come up with.

The annoying part is I can’t remember what my theory was. I’ve even gone back and reread the series trying to remember but all I can come up with now is the actual ending.
