Book to Movie

I have always been an avid reader, and as always I enjoy going to see movies based on books. Sometimes I have read the book and have been gravely disappointing with the movie (My Sister's Keeper), other times I have read the book and have walked away from the movie saying that is the best anyone could have ever wanted from a movie based on a book (The Road; The Time Traveler's Wife).
Recently Disney decided to make movies based on the Narnia Chronicles. That was cool with me. I had seen some BBC production years before and enjoyed it greatly. I had a few complaints, but nothing that I couldn't get past. Disney made "The Lion, The Witch and the Wardrobe", while not as good as the BBC version, it was still good. It was better for the graphics, I must admit. Then Disney went on to make "Prince Caspian", I was fine with this movie, until the last 10 minutes (I have noticed the last 10 minutes break or make a lot of movies). At which point I was almost got kicked out of the theater for the outrage that spewed forth.
Now Disney has gone and done it again, "The Voyage of the Dawn Treader" is coming out. Already I know some plot points are ruined, because of how they treated "Prince Caspian", but to add insult to injury Susan and Peter are in this atrocity.
I loved the Narnia Chronicles, I read them multiple times as a kid, I know how "Prince Caspian" works and what it means to the rest of the books that certain characters are represented when they should not be.
~Spoilers~
Let me explain the plot of "The Voyage of the Dawn Treader". Edmund and Lucy are staying at their aunt's house, they have an obnoxious cousin, Eustace. He continues to be obnoxious until he is carried off by a dragon at one point. The older siblings have stopped believing in Narnia. This became apparent at the beginning of "Prince Caspian", when only Lucy could see Aslan. Susan is especially annoying about Narnia saying things like "Oh that old game we used to play".
Now much later in the books Susan being a...brat, yes we'll go with that, means much more about all of the religious "under"tones within the series. ~MAJOR SPOILER DO NOT READ IF YOU CARE~ They all die and go to the world that has cast the shadow (which is the world we live in/Narnia/etc) except Susan who wasn't on the train and did not really believe all that non-sense. This means she didn't believe in Jesus and when everyone died she did not go to heaven, get it? Ok so hear is the problem, if she loves someone in the "pretend" world, how does she justify herself when she begins to stop believing? Is it a jealousy thing because Prince Caspian ends up with the star princess, and not with Susan. In fact Susan should be in her teens or possibly her 20's during "The Voyage of the Dawn Treader" and several years have past since "Prince Caspian" which means Prince Caspian aged quite a bit more than the rest of them. Try that one on for size, what was originally a match of proper ages is now gross.
~End Spoilers~
With all this rewriting of a classic, I can't handle it I am refusing to go see the movie. Feel free to do the same.
