I own only the Japanese DVD (which has English subtitles, but image details can succumb to moire patterning), so these are comments on the movie itself, not the UK release.
What has happened to Takeshi Kitano in the decade since 'Zatoichi', his much-deserved critical and commercial triumph? In that film he successfully counterbalanced seriousness and shocking violence with humour and humanity (as Scorsese also did in 'Goodfellas', say). By contrast, 'Outrage' offers unleavened brutality.
Gone is the stoicism of 'Sonatine', replaced with shouting and sadism. It's as if Kitano's character is the unholy yakuza offspring of Don Logan from 'Sexy Beast' and Nicky Santoro from 'Casino' -- unfortunately, no-one explained to him there are reasons why those characters, however memorable, are only supporting players in their respective movies.
I note that 'Outrage' begins with the Warner Bros logo -- presumably it is an international co-production, as was another below-par Kitano picture, 2000's 'Brother'. (But 'Brother' benefited from a jazzy Joe Hisaishi score at least!)
