Why I hate John Grisham

I will concede JG sometimes comes up with a good story. But many of his plots -- while interesting -- seem to have a fundamental flaw that I can't get over. Examples:

The Chamber - Young new lawyer takes on death penalty case of his uncle (or whatever).
The problem: the guy being defended *deserves* to die. I couldn't rally behind the cause at all since afaic, that's what the gas chamber is *for* -- to kill people who bomb churches and murder little black girls.

A Time To Kill – Dad shoots his daughter's rapists, goes to trial.
The problem: You feel for the dad, and root for him, but when he goes free in the end what we're celebrating is an extremely unlikely miscarriage of justice. His lawyer’s closing statement is basically that "vigilante-ism is okay because the crime was so heinous, and because you (the jury) would feel differently if the girl was white instead of black."

The Client – A kid witnesses a mafia murder in the woods. Now the kid wont' talk because he's afraid the mob will kill him.
The problem: their motivation to silence him would at its absolute highest as long as he *hasn't* testified. As long as the kid hasn't yet said anything, they can move freely (ie, they’re not arrested) and they have a huge motivation to bury the secret before it gets out.
If I'm a bad guy, and I find out my witness hasn't talked yet, do I think
"Cool, he hasn't talked yet. That probably means he'll never tell, so let's leave him alone on the chance that the most influential people in his life -- law enforcement, his parents, etc -- will be unable to convince him to spill the story."
or do I think
"Cool, he hasn't talked yet. I still have a chance to get off scott free if I can just silence him for good"
?
I'll tell you the answer: it's the second one.
As soon as the kid tells what he knows, their only motive would be revenge (not nearly as strong a motivator as survival). He'd likely be *safer* if he told since
a) Then the bad guys would have other problems on their hands (ie, arrest, defense, etc),
b) killing him would now be more difficult because of the scrutiny on them, and
c) killing him would no longer benefit them.
Every second you remain the Sole Holder of the Secret is another second where you are the Prime Target. It made no sense to me at all.

And beside all that:
1. He writes ludicrous dialog.
2. His sentence construction and general usage of language are amateurish. His vocabulary is miniscule. He uses words/phrases he doesn't know the meaning of.
3. He sometimes attempts to address issues (eg, poverty, racism) that he has only the barest understanding about, and comes off as an idiot.
4. It annoys me that he’s become fabulously wealthy peddling this crap to an undiscriminating public, while thousands of authors who are in every way his superior struggle to make a living at their craft.

But other than that, he's great .
