A dead-serious, non-winking faux-true crime doc about the (obviously fictitious) assassination of then-sitting president George W. Bush in Chicago, Death of a President takes a critical eye towards how American law enforcement replies to tragedy, particularly responses to terrorist attacks post-9/11. It's shockingly well-made stuff, blending news footage of all major players with some digital lip synching and re-dubbing (as well as an odd out-of-focus lookalike here and there) to create an enthralling, sharply-assembled, genuinely provocative and upsetting "documentary".
Loses steam during bits in the end of the first hour when President Cheney (!) starts running the show and things get a bit whacky, but it gets back on its footing for its venomous, barbed, nuclear-fucking-bomb third act that's among the most viciously, righteously angry things I've ever seen. Shocking and exploitative? Sure. An essential counterfactual? Absolutely.
