Regulators

The peaceful suburban life on Poplar Street in Wentworth, Ohio is shattered one fine day when four vans containing shotgun-wielding "regulators" terrorize the street's residents, cold-bloodedly killing anyone foolish enough to venture outdoors. Houses mysteriously transform into log cabins and the street now ends in what looks like a child's hand-drawn western landscape. Masterminding this sudden onslaught is the evil creature Tak, who has taken over the body of an autistic boy whose parents were killed in a drive-by shooting several months earlier. ([source][1])
