Oliver Stone's films need to be taken with a large dose of salt.

JFK is fine as entertainment; nonetheless, what is, I believe, a cause for concern is that an entire generation have now grown up to with that film -- many of whom accept its fundementals as 'history'.

It's the ultimate postmodern 'historical film' -- it suggests that any interpretation (including fictive) of history is valid.

Let's not forget that Garrison is by all accounts a pretty dubious individual known for Marcello mafia connections.
