There are some spoilers here.

I get it. Many parts of the book, like the beginning when he finds the first key would be really hard to make into a movie. I understand that. But then again, maybe this should never have been made into a movie? Here we end up with a movie that has some of the names in common with the book, but that is it. For those who has not read it, this might be good, but for those of us who expected it to be based on the book it is a disappointment.

For fans of the story: There is almost nothing from the book here. Lower your expectations, and you may not end up as disappointed as me.
