It's impressive that this was made outside the constrained studio system. This is not your ordinary thriller. It has a bit of a slow pace but it's deliberate; one doesn't realize they're being drawn into the film until midway through. Rachel Alig plays a perfect, unfeeling sociopath, with utterly emotionless dead eyes; even when her manipulative character "smiles," her eyes don't. "Granny's House" does become almost a very dark comedy of sorts in its third act, and while this feature may not be for everyone, it's worth a look or two.
