"Shocker" is mostly a mixed bag. The story has almost no development beyond the initial ideas, turning the film into an endless series of repetitive chases, and gets increasingly silly as it moves along. There are also too many action scenes which lack credibility to a point where that can't be forgiven (is Berg protected from bullets fired at him by an invisible shield?). However, there is also a particularly memorable sequence with the villain and the hero entering another dimension and fighting each other while jumping in and out of various TV shows. And Wes Craven's direction has enough energy to keep the film generally painless. (**)
