Debate of the Century

Which is worse, finding out it's all a dream or that it's all a simulation? I'm going with simulation. At least a dream might be prophetic. Meanwhile, over in the simulation thing, you know there's going to be ambiguity about whether the part outside a simulation is also a simulation. Ooh, so tantalizing!

Twisted Fantasy

The thing with dreams is, they aren't real. OR ARE THEY? They'd better be if the author bothers putting them in the story.

Addendum

Hey! This emerald is a fake!

The Most Shocking Revelation

"Nrevyw backwards . . . is wyvern! Our substitute teacher is a wyvern, and he's been killing the students to feed his young!"

The surprising part is that it isn't a disguised wyvern. It's just hovering there, eating people. But then you have to make the rest of the movie. Twists just don't get you very far.
