Oliver Stone's "JFK" is a masterpiece. I say that unequivocally. It's masterful filmmaking of a degree few could ever hope to reach, but it's been consistently plagued and overshadowed by the whiff of conspiracy fatigue ever since its 1991 release.
This has always been strange to me. Nothing presented in the film is all that far-fetched, and depending on your opinion of Dallas journalist Jim Marrs, it was all perfectly well-reported before Stone and screenwriter Zachary Sklar came along. Meanwhile, there has been a curiously strong push lately, it seems, to ensure once-and-for-all acceptance of the lone gunman theory, which, I'm sorry, if you've ever stood in the book depository and seen that vantage point (relative, as the actual window itself is blocked off), then you know the shot was pretty tough to pull off. And "back and to the left" seems pretty significant to me.
