So here's the deal, being a history student, I love the whole historical fiction genre. While the movie dragged a little, and the twist at the end was surprisingly unpredictable, it did however ruin the film. Throughout, the facts leading to the fictional tale of the assassination of J.F.K. seem some what feasible, however, this all goes to the shitter with the ending.
Wish there was a decent quote to throw in here, but really, it wasn't that kind of a flick.
