Query: Stupendously Bad.

The first 50 pages are funny. All the rest are dead boring. A bitter boring feud between writers that oozes nothing more than senility. After 100 pages this becomes one of the most morose novels I've ever read. You really can't stomach it after a while, it just plainly goes nowhere.A mixture of irrelevance, unfunnyness, and stupidity permeates you. A story about two bad writers written by a bad writer, and in the end who cares? Martin was never profound, clever, or imaginative, he was just funny occasionally and he's not anymore here.Thanks to the internet media this guy's hype has started to fade and people take him for what he is now, a very, very mediocre writer. Neither profound, nor clever, and certainly not imaginative. If you want to plough though 400 pages of garbage about two lesser writers squabbling by all means be my guest.
