There are some things that don't make sense, and this movie seems to be one of them. After reading reviews and one study guide for it, my conclusion is:
For those who argue that I need to see the movie in order to judge it, no, I don't. I have NEVER used drugs. Never smokes marijuana (nor any other thing, for that matter). I don't need to do drugs nor smoke marijuana to know that they are bad for me. And this movie is bad for me. It's been toned down to lure kids, but the other books are even worse.
END OF BOOKS SPOILER. DON'T READ IF YOU DON'T WANT TO KNOW PART OF THE END OF THE TRIO OF BOOKS.
At the end, the character known as God, who throughout the series is NOTHING like the One True God, who is merciful, loving, forgiving and all Powerful, this wimpy thing actually dies at the end. So, hey, if you want to waste your money on something like this dark movie, which doesn't edify, but will slowly erode the moral compass, along with all the other things that are being presented by Hollywood (most, anyway), then go ahead. But, for the price of a movie ticket and some snacks at the movies, you could, instead, help prevent malaria:
and know that what you're doing is saving a life. Better than ANY entertainment!
