I am a fan, for the most part. It's something that gets redundant pretty quickly If I watch it too much though.
I seem to feel a 50/50 split between being either rather good, or incredibly bad. Not exactly objective, and Clarkson's constant "Audi drivers are cocks" and such annoy.
Jeremy Clarkson is pretty much the definition of someone who has their head so far up their own arse that they still look anatomically normal.
