The thing I have to stress again is that the broadcast destination for this programming was BBC4, not a public channel, a very very specialised niche cable channel with an average viewing audience of about 6 people if they're lucky. And in truth if it IS post watershed why can't specialised programming still take place in appropriate formats, channels and times. Because the BBC was broadcasting pre watershed they pulled the De Frutos - a pity about the time slot, the De Frutos was the most interesting thing on the quadruple bill.
Thank you, Simon, that's worth repeating.
Like most people posting to this thread, I haven't seen the de Frutos but don't have any problem with daring or potentially offensive material shown on appropriate channels at appropriate times. If parents aren't minding the kiddies' bedtimes there's only so much broadcasters can be expected to do about that.
I couldn't find it again, but cubanmiamiboy's comment about art works and video game content is a good one.
