Okay, I have read the book 10 years ago, many were not very happy with the last book called the Last Battle that Susan was absent, so here are my thoughts on whether if she is going to be in the final book if they were going to make a movie of it.

Susan should be in the Last Battle

As mentioned, I wasn't happy with the ending of the Last Battle. In fact, the book also came under criticisms from famous author like J.K Rowling for promoting sexism. I couldn't agree more!
Many fans took to fan fiction and wrote their version of the ending itself, so for my case I would personally think that Susan should be in the movie version of the Last Battle. If some lucky person initiate a petition regarding this, I will be one of them to sign up!

Susan should not be in the Last Battle

Unless if the petition is denied, then we have no choice but to watch the movie instead. I would definitely dislike the movie even more if she is not in the film, despite that she was mention in it by her siblings.

While I have to agree that Susan should be in the film version of the Last Battle, here are my thoughts and what do you think?
