Penny- basically, the Blair Witch Project is a pseudo-documentary filmed by three teen-aged film students, about an ancient legend of a witch who lives in the woods outside a small Maryland town. They stumble through the woods for about three days while people yell at them from the darkness, shake their tents, and build odd stone symbols and stick figures for them to find and be horrified by. The dialogue goes like this:

Sean: My God! What is this f**king s#!t?!
Tom:This is some weird f**ked-up scary s#!T!
Linda:Whose s#!t is this,anyway!? This is f**king crazy!

That should give you sufficient knowledge to discourse intelligently on this fine film.
