World War Z the novel was a fantastic read.
Now, imagine you read How to Brew (I know, this is a stupid example, but stick with me for a second), and really dug it. And then a few years later you saw that How to Brew was being made into a blockbuster movie, with some involvement from Palmer. Then you went to see it, but instead of being about, well, how to brew, it was a romantic comedy in which the male star happened to drink a homebrew in a few different scenes, and maybe a fermenter shows up once or twice, but aside from that the movie has almost literally nothing to do with the book you read? You'd feel pretty let down, wouldn't you? You'd wonder why the heck they called this thing "How to Brew" when it bore little to no real relation to the actual source material.
This isn't aimed at you specifically because I have this argument with my GF all the time. I understand where you are coming from, I used to be a huge Stephen King fan and his books rarely translate well to any screen. But if it is the work of the author and he gives his blessing, then do you really have anything to be upset about? Or more specifically, you should be writing the author some hate mail about how he/she allowed them to murder the book. When it comes down to it, the literature is the work of the author and they can do with it what they like. For better or worse. And, unfortunately, they still need to get a paycheck, so if the book stopped selling, guess what, it's time to either write another best seller, or sell off what you've already done. The easy answer is to sell what already sells than to create another original work and hope it pays off without ruining your reputation.
I understand its the principle that counts, but principle doesn't pay very well.
