“Bad Impulse” (** out of four) was a scattershot psychological horror thriller about a husband and wife (Grant Bowler and Sonya Walger) who are viciously attacked in their suburban home and subsequently buy a home security system from a sinister salesman (Paul Sorvino) but this soon leads to him going off-the-wall and losing his mind. Too underwritten and undernourished to have any real bite although Sorvino as always adds some style and the strong cast helps to keep it watchable. One more imitation of “The Shining” that is a shining example of why that film was a classic in the first place.
