“Southern Scares” (* out of four) was a Southern-fried mess set in the 1990’s in which a video-store worker (Sydney Gowan) discovers a lost documentary left from her sister (Emma Gaines) with clues in all different directions and may point back to the family matriarch (Dee Wallace). Slapdash in the extreme and not the least bit scary (or even entertaining); even at only an hour-and-13 minutes, you can feel the padding. Wallace looks great at her age but it might be time for her to call it a day.
