She is using a rough generalization, which never leaves any room for exception. (And therefore wrong, in my opinion)

I sthink the difference between the two is the focus of the movie. A movie that focuses on suspense is a thriller (fatal attraction, for instance). Thrillers dont often have BOO! scares in them. Horror does. Thrillers also tend to be more dramatic. What Lies Beneath was a thriller, as was Poltergeist.

TCM is horror, as is Night of the living dead, Nightmare on elm street, Friday the 13th, etc. the focus is more on developing a feeling of dread, as opposed to suspense. Suspense builds tension, then has some sort of release. Horror builds dread, and offers no release.

Thrillers also typically end with a resolution that is favorable for the hero. Horror usually doesnt give you a happy ending, and if it does, usually includes a twist to hint that it isnt over.

There are obviously exceptions to these rules, but that is why i try to avoid using generalizations as concretes, as she did.

Oh, yeah, and thrillers don't necesarrily want to scare you, just make you uneasy and a little jumpy, whereas horror flicks aim to scare you, that is the whole goal. Maybe your teacher should do some more homework.
