If you are a believer in a conspiracy to murder John F. Kennedy and you have a scientific mind, you will no longer believe the conspiracy theories after viewing this special. The special supports all of its conclusions with compelling facts and evidence, directly disproving many of the fundamental assumptions of the conspiracists.
You will see many opinions by people who refuse to let go. But you will also notice that not a single one of them supports their objections to this documentary with any fact-based arguments. When they do try to argue fact, they are usually mistaken (example: reviewer Gregg Wager's assertion that this documentary does not mention the bullet that hit Gov. Connolly's wrist: untrue). Don't let them dissuade you from watching an excellently (and moreover, responsibly) crafted special.
