At the core of Doubt is a mystery: is Father Flynn a pedophile or not? Sister Aloysius (Meryl Streep) is certain he is. Sister James (Amy Adams) isn’t so sure. John Patrick Shanley’s movie based on his Pulitzer Prize winning play cleverly provides evidence for both interpretations. Philip Seymour Hoffman is at the top of his game as the likable priest who may or may not have a Dark Side. This is one of those movies you’ll be talking about long after you’ve left the theater.
