The screenplay, written by Stanley Weiser, plays up the rivalry between W. and his father, suggests at least one conspiracy theory, and dramatizes W.'s near-fatal encounter with a pretzel in 2002. But compared with Stone's paranoid take on the JFK assassination, the script lacks imagination. For the most part, it trots out well-known Bushisms ("I'm the decider," "shock and awe," "is our children learning," and "axis of evil") and seems content to re-create equally well-known events from Bush's presidency (pressuring George Tenet to produce actionable intelligence on Iraq, proclaiming "mission accomplished" on the USS Lincoln).
Spoiler alert: Bush gets the intelligence he needs, but the mission isn't quite accomplished. If you're not averse to a few other spoilers, follow Slate's handy guide straight to the good parts.
