I learned that lesson while enduring the seemingly-endless tedium of The Doors, and was reminded of it during some of the long, drawn-out portions of JFK.
Admittedly, he has taken very personal points of view toward controversial subjects in several of his pictures like "Platoon," "Salvador," "Wall Street," "Talk Radio," and "Born on the Fourth of July"; and he has been stylistically over-the-top in at least one picture, "Natural Born Killers."
The style of “JFK” colored many of the films that followed (including the better ones like “Natural Born Killers” and the real stinkers like “Nixon”).
Oliver Stone has directed a number of fine films, many of which you could call “prestige pictures,” that have included “Platoon,” “Born on the Fourth of July,” “JFK,” “Nixon,” and “Wall Street.
To these ends, Stone employs the techniques—shifting film stocks, color filters, unnatural camera angles, non-diegetic inserts, and so on—he used to such success in JFK and, later, Nixon .
Reteaming with Oscar-winning JFK cinematographer Robert Richardson, Stone shoots Killers in 35mm, 16mm, 8mm, and video, cutting amongst them like a Super Bowl director.
