This could have been a great movie; if it would have had a theory to analyze. I personally believe that LBJ along with the Military-Industrial Complex & the Business establishment had him killed, because he wanted to get out of Vietnam, JFK wanted to cut the oil depletion allowance, and wanted to dump the Federal Reserve. He was a large threat to the Texas Oligarchy that essentially runs the country. JFK was killed more due to economics than anything else. I am well read on the subject for more than 20 years. The Texas Oil Barons were also huge lobbyists for the Vietnam War.
I do think that this film was better than Ruby (1992). I do not think it was as good as JFK or Executive Action or The Trial of Lee Harvey Oswald (1976). I think that Executive Action was the best in this genre. Flashpoint has a lot to say about our government & about life. It's cynical but also very entertaining. It was actually better, than I thought it would be. The film was also way ahead of its time in predicting the surveillance state of the Federal government. Really good performances from Torn & Kristofferson. Don't miss this one.
Other than that, a reasonably solid story.
