I don't understand the low score.
Granted, Shawshank Redemption it is not. However, it at least fits the bill of decent gorefest. It creates a solid atmosphere and although the premise is certainly questionable, it's handled with decent production values and appears to have been taken at least somewhat seriously by the cast. I'd put her in at least 5-ish territory.
