Bloody Birthday is an open invitation to revel in three of the most mean-spirited children in horror.

Inoffensive, rather inconsistent but watchable all the the same.

"Bloody Birthday" isn't a normal 'creepy kids' horror movie, where the murderous children are pasty and blank-faced. No, this trio of pint-sized psychopaths plots out their crimes, takes the time to set the stage, and cover their tracks.

It's dazzling the way the film cleverly portrays childlike innocence to draw viewers into a false state of security, while then, when they least expect it, revealing the characters' lack of conscience.
