How many people learn their history from Hollywood, and believe that the films are a reliable and factually accurate account? (Come to that, how many people believe that history itself is necessarily without perspective ...?)
If the films inspire some people to learn more, or at the very least, to gain an awareness of an incident in the past or a significant person which they didn't previously have, then maybe there can be found some merit in them, whether a dog be called Digger or Snigger or Bigger or any other of a number of rhyming (or nearly so
) words.
There's a large Barnes Wallace statue at Herne Bay, incidentally - he did quite a few trials of the bouncing bomb there.
