I'm a massive fan of the Holy Grail. I think it trumps the Life of Brian. So I should hate this parody.
But I don't. i love it. I don't know why Monty Python let them do it. It could have been horrible. But it's great - faithful enough in detail (the structure of sorcerer is perfect), but different enough to make it its own.
Isn't there a St AAaaaaaaargh in Cornwall?
