Clarkson is a twat on Top Gear, but he has made some other documentaries which have been very good.
I really liked his Brunel one, and the one where he traced his family (only saw a bit of that, hence my slightly vague description).
He seems like an intelligent sort of chap, who makes his money by appearing to be an oaf on a programme about cars - which is probably a commentary on society or something.
It's interesting to see the Top Gear clips above, which date from a time where the "Clarkson bit" of the programme was precisely that - a short "humourous" interlude between serious things about "motoring".
