- 1996, Peter Travers, The Rolling stone film reader:
  For an exhilarating period, until spectacle and sequelitis restored formula to the throne, experimentation became big box-office.
- 2000, Derek Elley, Variety Portable Movie Guide:
  Suffering a bad case of sequelitis, this Sister Act follow-up is too formulaic and frequently pauses to sermonize at the expense of entertaining.
