My point was that the film presents as  mass entertainment rather than as a sober documentary history - and therefor shouldn't be taken seriously as a record of the period

Did you really think anyone here was likely to think of it as "sober documentary history" ?

but should be seen in the context of the of current political/ideological battles in the US.

Like the one you've been fighting here to defend the US's covert intervention in Afghanistan for example ? :-)

Maybe it's because I'm a Londoner - that I moved to Nice.
