An oldish woman (Nana Visitor) leaves a psychiatric facility to surprise her estranged son's family on his daughter's 8th birthday. She promptly murders the nanny (Lexi Atkins) and steps in to pick up her slack. The son (Brett Zimmerman) has misgivings, but his wife (Kelly Sullivan) overrules him and lets grandma move in and care for their kid while they are at work. This movie was super unbelievable. Grandma is old and rail thin--there's no way she could overpower the people she attacks in this movie. Also, the husband telling his wife he thinks his mom--who just got out of an insane asylum--is dangerous and the wife blowing him off and entrusting her kid to the woman's care is ridiculous. That said, I thoroughly enjoyed the movie. It's full of pretty people; it's well shot; and the story is entertaining and fast-paced. Jessica Blackmore (Wicked Mom's Club) plays a supporting role.
