“Better Watch Out” (* out of four) was a nearly unwatchable horror thriller about a young babysitter (Olivia DeJonge) who is hired to watch an annoying brat (Levi Miller) for the evening when there is suddenly a home invasion and him and one of his even more annoying friends (Ed Oxenbould) hold her hostage and torment her. Anyone who makes it to the end of this mess will know exactly how she feels. Unusually mean-spirited and unpleasant film plays like a junior-high school version of “Desperate Hours.” Everyone has to pay the bills but one time great character actress Virginia Madsen (who plays the boy’s mom) should surely “watch out” for dreck like this.
