It's been more than a decade since "The Blair Witch Project" showed us that you can rearrange some bundles of sticks in a movie and make hundreds of millions of dollars.

It invented a genre known as "found footage horror" - the idea being that audiences will be more scared and more forgiving of a low budget if they can convince themselves what they're seeing is real.

"Grave Encounters" is the latest entry, and with more than 9 million views of the trailer on YouTube, it has breakout potential.

A cast of unknowns portrays the crew of a "Ghost Hunters"-style reality show. As explained by a TV producer, the film was compiled from the last footage they ever shot. Of course it is.

And the whole thing takes place in a former mental institution. Of course it does.

"Blair Witch" had one of the first viral internet campaigns for a movie and convinced an awful lot of people that it was real.

We're not getting fooled again, but "Grave" will definitely get a lot of audience screams and jolts.

It's a cheap gimmick (literally), but directors The Vicious Brothers create some truly creepy moments. Forgettable characters keep it from being more than a fun-house ride, though.
