Ichi, scratchi
Regarding Auntie Beeb's bait 'n' switch approach to article linking, comes this case in point: the rise of ultra-violent Japanese films is discussed in How Ichi the Killer brought ultra-violence to the mainstream
. The link from the BBC home page teases: The most shocking film ever made?
Ichi the Killer may indeed be shocking, I can't comment, I haven't watched it. But A Clockwork Orange introduced ultra-violence three decades earlier, and was completely banned in some countries for years.
In reality, the article's just a lazy attempt to get people to read, or half-read in my case, James Balmont pimping the British Film Institute's Japanese film season. How drear.
