I think this is an interesting discussion, and it illustrates how tricky it must be for the BBFC to rate films on our behalf.
These are some of the factors that I believe can be seen in the BBFC's judgments on
violence in films. (Presumably there are similar factors regarding judgments on sex, nudity, language etc.)...
- Whether the victims/perpertrators of violence are human/human-like.
- What the visual impact of the violence is (how bloody, severed body parts etc.)
- What the conceptual impact of the violence is (whether it illustrates psychopathic/sociopathic behaviour).
- The extent to which violence, the threat of viollence and violent solutions dominate the film.
I think in each of these respects, TDK is very much like The Matrix. The use of weapons is more prevalent in TM, but the targets are not actually human. Perhaps if TM were released now it could be a 12A?
And that's the point - this is not about censorship. No one is saying that TDK should be banned or cut. Simply that (a) it is unsuitable for young children, and (b) the state certification agency should rule on that.
And behind that (and other recent decisions) is the question as to whether the 12A certificate is "fit for purpose" and whether more and more adult-themed films are being placed in this category, even where they are clearly inappropriate for young children. (And the inherent contradiction in the marketing to children of adult films probably neeRAB sorting out, too).
If the BBFC wants to continue in this direction, perhaps we need a 12F category - 12A films that are potentially suitable for a family audience. In that category, I'd place the LOTR trilogy, and the Harry Potter films, Spiderman.
