I was honestly offended at the quality of a recent episode about fire prevention in skyscrapers. It was 50% sales pitch for a new system a professor at Edinburgh Uni had come up with for preventing fires but then degenerated into yet another September 11th tribute.
Utter tosh, it was as if they'd run out of interesting footage after 20 minutes and just rehashed some old news footage with professional interviewees recounting their experiences (again)
And don't get me started on BBC Focus magazine, before it had the BBC moniker it was a decent magazine, now it just panders to the masses.
