What explains "My Soul to Take," Wes Craven's latest dead teenagers movie?

Did he turn this incoherent fiasco in as incomplete? Did the studio sign off on a horror movie based on the words "We can do it in 3-D" in the pitch?

Or has the "Nightmare on Elm Street" and "Scream" director has finally gone off his rocker?

This waking nightmare is a puzzle with no solutions, a twist that isn't a twist at all. And it demands concentration, primarily because it makes little sense.

"Soul" is a variation on the "He's coming back to kill you" formula, set in a town absorbed by the legend of a mass murderer everyone thinks drowned 16 years ago. The teens of Riverton High celebrate "Ripper Day" every year, starting with a beer-bust candlelit vigil in front of the hulk of the burned out ambulance where the Riverton Ripper was last seen. They chant at the river — "Make yourself known!" And they taunt the seven kids who were born the night he died to vanquish a puppet version of him at midnight on Ripper Day, thus protecting all the youths and the town for another year.

Brandon (Nick Lashaway) is the jock bully. Penelope (Zena Grey) is the devout Christian who thinks "The Lord's Prayer" will protect her. Brittany (Paulina Olszynski) is the spoiled mean-girl blond. There's the blind kid Jerome (Denzel Whitaker) and Jay (Jeremy Chu) and the bullied, put-upon Alex (John Magaro).

And Bug (Max Thieriot) is the sensitive one, the kid who has nightmares, who dreams of deaths and who wonders if he's losing his mind. He's Alex's best friend, and no, we don't know why they call him "Bug."

It's a high school run by the pale, mean girl dictator Fang (Emily Meade, pretty and pretty unconvincing), who determines who gets to be bullied today, who goes out with whom, the works. Only the fearless Penelope can save Alex from a beatdown. "Do NOT bring the wrath of Jehovah down on you!"

But it's a high school where everybody walks home from school and every walk goes through the woods. And this is the year when the kids don't complete their ritual "slaying" of the Ripper. So kids are picked off, in bursts, over the course of 100 or so minutes.

The finale has one of those "Let's explain everything" blasts of exposition that is supposed to forgive the clutter and mess in front of it. And the one thing finale doesn't explain is how "My Soul to Take" got into theaters in this sorry state.
