Is it really that bad if Hollywood is somewhat discouraged from following the latest villain-du-jour trend? As a German, it became somewhat tiresome in the 80s, although we obviously still deserved it (and much more). Then 9/11 got others into the hot seat for a decade. This being fiction, any decision to give your villains some distinct national or ethnic identity seems suspect. I guess it’s fine, or at least necessary, I’d the fabric of the plot (Godfather, or that series where Hitler had won WW2). But if it just serves to tell apart good and bad guys by their accent (Die Hard), it seems like entirely unnecessary vilification.
