What makes it different from others?

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

A movie that not only functions as a solid scarefest but a razor-sharp satire.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.
