NOTE: This post contains spoilers about both the movie Harry Potter and the Goblet of Fire, and the books that follow it. If you don't want to know details about the movie or the books that follow, do not read this post.
My good friend C.K. ranted in a recent post about how the biggest problem he has with Harry Potter and the Goblet of Fire is that Harry doesn't really do things in the story - things are done to him, and he reacts to them. Then C.K. wonders whether it makes a diff that he hasn't read the books, and alleges that, if so, that is yet another fault with the movie.
No, C.K., it isn't. The Harry Potter movies take lengthy books (734 pages in the hardcover version of Goblet of Fire) and condense them down into just over 120 pages of script. Naturally, there's a lot that's left out. Furthermore, you have to view Goblet of Fire within the context of the overall story arc of the Harry Potter series. Author J.K. Rowling had all seven books outlined before she wrote the first book. It's not a story arc that's been randomly pasted together as she went along; each book, as it is written, has its place along the arc that leads to the resolution (of some sort) in Book Seven.
