Why change the story from tobacco to guns?
In the book, the villain is a big bad tobacco company. In the movie, this is changed to a gun manufacturer.
Why? The filmmakers obviously had an agenda. This wasn't merely an entertainment decision.
Much like the recent film Miss Sloane, this came off to me as little more than anti-gun propaganda that had little respect for the 2nd amendment. Just like in Miss Sloane, it's the anti-gun people who are cast as the dutiful heroes, and anyone who supports gun ownership is a nefarious asshole who has no regard for human life.
If I had known this is what the movie was going to be about, I wouldn't have even bothered with it. But once started, I felt like I should go ahead and finish it.
Pushing all that aside though, just as a movie, I'd say it was . . . okay. It was more of a Hollywood thriller compared to most other films based on Grisham's books. The plot is far-fetched and I almost had to laugh at Hackman's team's ability to just magically pull up any information they want to on any person at any time, like they operate the eye of God. Also, the film is a little hard to follow at times. I believe one review I read called the film "overplotted." I suppose that's as good of a way to put it as any.
This is definitely a lower-tier Grisham film for me. It's certainly no Rainmaker.
