I had assumed that this film was going to be just another Kennedy hagiography. But really, JFK came off as less decisive, and somewhat unsure of himself. In fact, it made it look like Kenny O'Donnell saved the world. Costner and the rest of the no-name cast did OK. About Costner's Boston accent; at least he tried. Not everyone can be Meryl Streep. I'm a Southerner, so if he murdered the accent, I cannot tell. But it would seem silly for a movie about all these Bostonians to have characters that all sound like they're from Nebraska or California. It'd be a little like those films with Arnold Schwarzenegger playing an (native-born) American. The action scenes with the planes and ships were well-done. But overall, I'd say this movie is not as good as "The Missiles of October". Grade: C-
