What is the name of this kids halloween movie?

[Angela]

There was this movie that my daughter watched around haloween that was on cartoon network but it wasnt a cartoon. It was a real movie and it was started out with this girl who had to take care of her younger brother while her parents went out and all kinds of crazy things happened. I think they read some book or something and monsters appeared. My daughter really liked the movie but I cant remember the name, Help!

R.L. Stine's The Haunting Hour: Don't Think About It (2007)
aka The Haunting Hour: Don't Think About It
aka Don't Think About It

IMDB synopsis:
Emily Osment plays a 13-year-old goth girl who is trying to fit in at her new school. To entertain herself, she plays a series of pranks on the popular kids (Brittany Curran from "The Suite Life of Zack and Cody" and Cody Linley from "Hannah Montana") and her younger brother, Max. When she goes to a Halloween store looking for new tricks, she finds a book titled "The Evil Thing", about a monster that will be summoned if the reader thinks about it. Yet, if you try not to think about it, you might find yourself unable to think of anything else! That's when the spooky adventure begins.

I thought that the ads looked so interesting that I decided to watch and videotape it. I'm happy that I did because it's an impressive horror film that likely would entertain many adults, too~especially considering the ending.
