“XX (** out of four) was a lukewarm horror-movie anthology about four separate stories; in the first, a boy looks into a box and then refuses to eat and gets very ill. In the second, a dead body is discovered shortly before a birthday party causing everyone to panic. In the third, four friends on a trek in the desert uncover a painting that unearths an evil spirit. In the fourth, a concerned mother finds that her strange son has become the spawn of Satan. None of the stories are worth watching, although film is mercifully short at only 80 minutes. Movies like this make you appreciate “Creepshow” and “Tales From The Darkside” that much more.
