I didn't have too high hopes for this movie so was pleasantly surprised when I watched it as it exceeded my expectations.
Story 6/10: The story is a side story to go along with the series. You do not need to watch this movie in order to understand things in the show. It is an optional extra that I would recommend.
The basic story is Saki and Mai are going to perform in a karaoke contest when a new bad guy from Dark Fall interrupts this by invading the Land of Clocks and stopping the World Clock. This stops time everywhere. Only spirits and the Precure can
move but if they don't fix the World Clock in time they will stop too. So Saki and Mai travel to the Land of Clocks to stop him and help the clock spirits Minutes and Hours start the World Clock again so time can continue before it stops all together. The 'bad guy''s motive was to rule over the world in silence with just him there which is a bit of an odd boring motive but ah well.
Art 9/10: The art was a LOT better in the movie than it was in the show. I was quite impressed with the backgrounds and animation. It was smooth, well drawn and animated. Very visually pleasing.
Sound 8/10: I liked the sound. Precure generally has good music. This had a more orchestral sound to it, fitted the movie well.
Character 6/10: Saki and Mai were Saki and Mai. They did argue quite a lot throughout then realised how good friends the are ect the usual friend strengthening plot. The spirits were the spirits. Minutes and Hours were very cute and enjoyable. The new villain didn't have much backstory apart from that he was from Dark Fall and little development. He is what lets the characters down, just a generic unexplained villain with a bit unusual and boring motive.
Enjoyment 7/10: I enjoyed this movie a lot more than I thought I would. It was a pleasant watch that kept me entertained with decent enough characters, great animation and music. It is a nice little add on extra for the series. I have seen 4 Precure movies now and I have enjoyed this one 2nd most.
Overall I give it 7/10.
