I don't know how you can even say this movie lacks a strong conclusion. This is one of the very, VERY few movies to ever actually make me cry. Can you ask for a stronger conclusion than what we are offered at the end of this? The end ties together everything perfectly, going all the way back to the beginning of the movie! I mean, the fact that we finally get to see what was in the witch's eye (regardless of the fact that it was all made up) is reward enough. Not to mention that we find out throughout the last bit of the movie that not EVERYTHING Edward Bloom told was a lie. All I can say is, the beginning and ending lines about the fish really tie the movie together, despite a few comments from non-fish lovers!!
All in all, one of the top 3 movies I have ever seen!
