Boy, a lot of people disliked this movie. It suffers from the strength of its predecessors. It also suffers from too much for one film. We don't get enough psychological foundation, for one thing The bad guys have way too much power and this thing they can launch is pretty hard to swallow. Imagine that she and her sister have the future of the world in their hands. Thirdly, it is based on a book, written after the original series (an average book but entertaining). the problem is it ignores major plot elements. I doubt we'll see any more of these films.
