Set in New York City, the epicenter of a phenomenon cropping up in communities across the United States, “Nursery University” provides a good-humored look at the oddly competitive environment of nursery school admissions. The film tells the story of five families -- each with different backgrounds and economic circumstances -- attempting to place their toddlers in preschool classrooms with limited spaces and high price tags. “Nursery University” also follows the school directors who must determine which “applicants” to welcome through their doors. Cue the tears, hysterics and breakdowns -- and that’s just the parents.
