At least Child’s Play makes the effort to explain what forces exist that might bring plastic and stuffing to life. In true horror fashion, it is not the Christian god, but forces that are somehow more powerful, more malevolent. It would hardly behoove the maker of all the universe to inhabit a Cabbage Patch knockoff. The Lakeshore Strangler has been in training to cheat death and remain alive forever. He takes lessons from a mystical character whose religion is referred to only obliquely, yet whose efficacy is obvious in the malevolent toy. Willful suspension of belief is necessary to make this resurrection story plausible, but that disbelief must include belief in religious powers. The horns of this self-same dilemma hoist all religious believers in a scientific world.
Chucky is participating in one of the oldest of all religious traditions—death avoidance. Some of the earliest evidence that we have showing that hominids were developing religious sensibilities is the burial of the dead. There is really no reason to bury if we are only carrion like every other meat-based product. Whether it is out of fear or reverence, we turn to religion to assure us that there’s something more. It may not be scientific, but that’s largely the point. For many even today, a concluding scientific postscript leaves a body cold. Time for a leap of faith. Horror films are often decried as lowbrow and unsophisticated. Chucky, however, like many mythic monsters, is rapping his inhuman fingers on the door of religion. Specifically resurrection. Although in this case, it might be best to keep that door firmly closed.
