As such, it's powerful. And letting the protagonists mostly speak for themselves is insightful, even if it leads to some generalisations. A journalist, for example, condemns all journalists working under apartheid as tainted by the system, even those who wrote on theatre - well, perhaps those writing on cooking weren't. He forgets the brave work done then by newspapers like Vrye Weekblad and Weekly Mail, and they didn't even have a cooking column. A documentary like this, though, tends to date as soon as it's made.
History goes on.
