The only Grisham movie I ever liked was Coppola's THE RAINMAKER adaptation (hell, the author thinks its the best of the Hollywood movies based on his books).
I read The Firm, The Rainmaker, and A Time to Kill. Going by the novels, The Rainmaker was the best adaptation and in my opinion the best movie without comparison to the book. I also enjoyed A Time to Kill in both formats.
I never liked The Firm. The only reason it put Grisham on the map is because he took a common formula of a thriller and added the whole law firm aspect. So it seemed new to people, but it really wasn't. A Time to Kill and The Rainmaker actually had heart which set them above The Firm.
