If I had to choose one thing about the CCS series that was good it would be this movie. Not just because it signifies the end of the series :P but it was a short wonderful story that actually wrapped everything up very well. Shoujo fluff at its best in this movie and that says a lot coming from me because i generally hate shoujo.
Unlike the show this movie kept up a good pace. nothing was too slow or to fast plot wise and it was wonderful to watch the events unfold and if you are a fan of shoujo you will be on the edge of your seat waiting to see what will happen at the end.
