It is a story that knows exactly how stupid it is, and that means it can get away with anything. It’s just played so straight that half the target audience misses the joke. That’s like if Bored Of The Rings was somehow more popular and enduring than the Tolkein novels it mocked - the high-fantasy tropes are still there, and the book does function as a hero’s journey. It just stars Dildo Bugger and his son Frito.

The measure of any adaptation - if that somehow exits development hell, one of these decades - will be the car chase in the middle. If they show it, they’ve failed.
