From the perspective of someone who doesn't know horror at all:

I am only positive of #2 because it takes place at my alma mater and was therefore required freshman-year viewing. I haven't seen them, but I'm pretty sure of 3, 13, 18, and maybe 4 and 8. Is Blair Witch there? Because I've actually seen that but none of the descriptions seemed to fit at first glance.

megan, as someone who likes horror, and has seen quite a bit, I've so far only figured out 14 out of the 20.

I think my favorite was the clue for number 5, as it perfectly pinpoints the part of the plot that carries the main theme and message of the movie.

I don't even have to look because I know which one you're talking about, and that's my favorite too. Very clever, and pretty much requires actually having seen the movie rather than just knowing the basic premise. (So it's sort of a cheat since it's not so much a "synopsis" of the movie itself, technically.)

When I was watching the movie for the first time a while ago, I thought, "If that happens, this movie will be so awesome." And I was so surprised and impressed it actually happened.

And megan, I guessed your whitefonted one was number 9.

Upon re-reading, I realized that too. Also, that I've seen 6 and 11.

Oooh! Those were two I didn't know, or was at best very tentative about.

I just made a guess at 11, and I have no clue what 6 is. I'll probably be kicking myself when I find/figure it out.

11 is The Others. Great movie.

That was my guess, P-C.

See, I felt stupid about 6, because I think it is actually very obvious, given the subject matter. But maybe I'm just wrong like a wrong thing.
