There is a danger that a lot of the satire in 1984 is missed because of a lack of historical context.
Indeed - and as someone whose job it is to study surveillance, I do get a bit weary of all the 'Big Brother' analogies that are thrown around. Orwell didn't write
Nineteen Eighty-Four (not 1984 BTW - pedant's point!) as a predictive novel, however much elements of what goes on now seem to resonate - as do elements of
Brave New World, or Kafka's The Trial. You really need to talk to some people who grew up in Eastern Europe at the time of Stalin to understand this - a colleague of mine, a Polish dissident who now lives in Canada tends to be quite short with people who think there's no difference...
Orwell was very influenced by Zamyatin's earlier satirical dystopia,
We ('My' in Russian). That too is worth a read, and it is worth watching George Lucas' first (and best) film,
THX1138, which draws significantly on the same source. I'd certainly agree that the 1980s film version,
1984, is good.
