Children of the Corn 7: Revelation (2001)

Jamie hasn't been able to get in touch with her grandmother and decides to visit to make sure she's okay.  Her grandmother lives in a seedy apartment building right next to a cornfield.  The few neighbors left in the building and the front desk person haven't seen her grandmother in awhile and aren't any help.  So Jamie decides  to file a missing persons report with the police.

After she decides to stay in her grandmothers apartment, Jamie goes to the local supermarket where she meets some creepy Amish type kids.  The kids keep showing up wherever Jamie goes, and keep getting creepier since they never say anything, continually stare at her, and seem to appear and disappear in the blink of an eye.

There are children and there is some corn, but that's about the only connection this has to spooky kids killing people in cornfields.  The movie mostly takes place inside the rundown apartment building.  Also I thought this town was in the middle of nowhere but there are skyscrapers and a large city in the background which makes the lack of people and police all the more strange - but not strange enough to be interesting.
