All I know is that Ollie Stone's movie was fascinatingly unpersuasive at proving that gay Republicans were the ones who actually masterminded the assassination and that they framed Oswald.
Stone presumed his movie would create a wave of science using modern technology that would "uncover the truth" and prove that there was a conspiracy, even if it was not the one he presented.
Ironically, he was right. There has been a wave of science on this and new discovery, all of which has been rather damaging to most every conspiracy theory involving the number of shooters and whether Oswald was the primary culprit.
