Stereotypes
Okay, it's bad enough that the grieving parents, the spooky kid, and the mad scientist stereotypes are present...that's to be expected. Well, maybe we were hoping for something better.
But WHY does the only black character in the movie have to me a menial domestic, who has premonitions of evil and attempts to murder the child in her care? Hell, she isn't even sophisticated enough to know not to open her door to some strange dude knocking on her front door!
