@c188e6a8 I bet you're right. 
My mother often says that she doesn't like to see a book-based movie after she read it, because it lacks details, some things are willingly changed, etc.

I may be able to judge it soon : I found in a public outside book box the Crichton's Jurassic Park entire book. I took it instantly home, I love the first film !

Do you often read ? 

 @4f8c96b3 I just got back into reading a couple of years ago, but still don't do it nearly as much as I did when I was a kid.
