We all know the plot. A 12 year old normal girl slowly turns into a raving, supergirl agent of the devil, a freak so outrageous that she , and the movie, are really more science fiction than horror! If anyone really believes this stuff happens, well that is up to the viewer, not to mention the ideas of Roman Catholicism. Ellen Burstyn does a great job as the very bewildered, near celebrity actress/mother /recent divorcee thrown into this very ugly vortex of surreal primitivism. Also note the very antiquated medical equipment in the hospital. Definitely, 2000's medical procedures have improved in 33 years! The special effects are excellent, if you don't mind some rather disgusting bodily excretions! Also some interesting Georgetown,DC scenes. Worth a look if you can hold your nose, and forget reality for about 90 minutes!
