"Children of the Corn III: Urban Harvest" is a somewhat tacky and unnecessary sequel to the moderately successful Stephen King adaptation and its slightly under-rated sequel.
In the film, two youths from Gatlin (the setting of the first two films) are taken in by a yuppie couple in Chicago. The older of the two fits in relatively well, but the younger has plans of his own. Planting a corn field in the abandoned property next door, he creeps out his adoptive parents and eventually converts the entire teenage population to his maze worshipping cult.
Despite a predictable plot that seems to be missing chunks (at what point did Eli win over his peers?), dodgy special effects and wooden performances by its relatively unknown cast, the film is moderately enjoyable for what it is. If you want to see some brutal and over-the-top death scenes committed by vegetation, then "Children of the Corn III" hardly disappoints. Elsewhere, however, the film comes up short, and that's all there really is to it.
The film was dumped in theaters briefly in 1994 before being thrust into complete oblivion, making room for four direct-to-video sequels and a made-for-TV remake. Look closely, and you'll spot Charlize Theron in her very first role as an extra.
