The main character is SO ANNOYING...
Her high-pitched baby voice, her nonstop prying, and the relationship with Cynthia were all horrible. The whole banter between the two of them over Jessica's internet use and Karen's disappearance was grating to say the least. Cynthia was just nasty and Jessica was just beyond irritating.
Also, to be kind of mean, the actress who plays Jessica has terrible skin. Not to say any of us are perfect but usually the characters in these movies are at least attractive.
