Very much of his time mickrog.
Allen's material was considered quite provocative at the time - he was the Frankie Boyle of his day, as hard as that is to believe now - but all topical commedians operate within their timescale - what was shocking then is tame now, and what is shocking now is ... unlikely ever to seem tame!
I do find that Frankie Boyle has not only stepped over the line of acceptable humour - he has destroyed it completely.
That said, I think the furuore he has caused is due entirely to his being given a platform to offend a TV audience.
Interestingly, Chubby Brown, who is and has always been a user of provocative language - although not controversial in terms of content, which remains static - has been steadfastly refused any TV airtime, an unwritten understanding that his material is unsuitable for the medium, and his audiences enjoy his work through his massively successful live shows and DVD's.
Given that Boyle adopts precisely the same approach to his material as Brown - this is what I do, laugh or not, your choice - I fail to see why Channel Four broadcasts Boyle's stage shows, and then wonder what all the fuss is about!
You can't claim to be a 'cutting edge' TV channel and broadcast unacceptable material to the nation, and then wonder why the nation is upset with what it receives.
