Spoilers

Oh and Deckard being a replicant isn't a spoiler... you have to piece it together for yourself and come to your own conclusion!

Basically your list is like High School Musical.

harsh, hahah.. although i think the donnie darko comment is also an opinion type of thing.. there is no real conclusion of how he knew what was going to happen.. whether it was a dream or he went back in time..

The reason I think it was just preminition is because we saw the plane get sucked through the vortex thing, we didn't see anything happen to Darko as I recall. Not seen it in a while though.
