I loved JFK, and thought it was a truly important film, then I researched into it, and discovered that most of it was made up by Oliver Stone. Shame, because it was a brilliant film.

My standard (cliched) response...'it's a movie'. At least it provoked you to expand your understanding of the subject.
Obviously it's a controversial film....but also I think somewhat misunderstood. The story's told from very much from the POV of Jim Garrison who was himself a highly controversial figure. Of course Oliver Stone has an agenda...he portrays Garrison as something a hero...and predictably he tries far too hard to tie it all in with his pet obsession - the Vietnam war. It's certainly conspiracy theory propaganda....but then it is, after all, the story of a leading conspiracy theorist.
For all that, as you write, a very skilful piece of cinema and a very influential film in a number of ways.
