I really don't know what to say, the movie was defintely wonderful and yet easy to scorn at the same time. The plot and scripting are ridiculous, unbelieveable fluff. The acting is the standard horror movie type -- the acting people who got a role in a low-cost flick and were never seen again. However, the movie is fairly good. It has some low-grade action & suspense but Child's Play is easily much better. This movie, to its credit, was the victim of production in early 1990's, when SFX were less advanced. If the movie were remade today, it'd probably be much more than a three-stars average flick. It does shine in some parts - the Jessica / dollhouse scene is great, the Housemaid's killing is sad but brutally gory, and the rest of the film is a bit weak and struggles along to support a weak plot.
Maybe you should rent it, but don't buy it!
