Freaky (out Nov 12) is a horror-comedy about a vicious serial killer (Vince Vaughn) who swaps bodies with one of his intended victims, a high school senior (Kathryn Newton). Vaughn wins laughs impersonating a teenage girl but the script doesn't make enough of the cool concept. There are poorly fleshed out subplots (e.g. an alcoholic mother) the finale is weak, formulaic. Grade: C+.
