In order to really appreciate fine foods, you sometimes need to sink your teeth into a really awful, greasy hamburger drenched in ketchup.
In order to really enjoy fine writing (but what is fine writing? I'll get back to that), you sometimes need to read a real turkey.
Read Nick Lowe's hilarious article "The Well-Tempered Plot Device" for an explanation of how bad fiction uses plotting (and pick up a few desperate tricks, in case your plot gets stuck).
And you must read these equally hilarious quotes from the books of Lionel Fanthorpe, the Ed Wood of science-fiction literature. He's not merely bad; he elevates Bad into an artform. (CAUTION: Do not drink anything while reading the quotes!)
