A good halloween movie for this year is the most recent DVD release of
stephen King's 1408.
Our daughter favorites are Wes Craven's
Scream trilogy. Her and friends watched all three of them recently at a sleep over. Nothing like several 11-12 years old screaming every few minutes.
The scream movies are not true horror movies, they are just as much fun as they are horror, so 11-12 year olds really don't get too scaried, it just gives them reason to scream just for the fun of it.
