Overly long (especially since I watched the director's cut). Too many F bombs (my guess is about 70 in the director's cut; I don't know about the original cut). Otherwise, great movie. I'm surprised I was allowed to see it--not for kids under 16.
My rating: R for a brief violent assassination footage shown throughout, frequent language/drinking/smoking, and for a scene of nudity.
Well to start off, the language is horrible, with almost non-stop use of f--k, a lot of sexual references, but the movie really makes you think about Kennedy, and his assasination.
