I have to say this was a really great movie and so beautifully animated from such a great series. I scanned through some of the first movie, and I'd have to say it was a HUGE disappointment for me according to the series. The first movie just didn't seem anywhere closer to its original series. It was much too fast-paced and I could not understand how the plot went. But this one, I picked it up from the library, looked at the screenshots and I was nervous this was going to be worst than the movie, but as I watched it, it appeared to be more greater than the first movie. Seriously, it's like it follows the series. Sakura falls in love with another boy and she tries to dictate her love to him.
Animation: Well, the animation has gotten a littlle grimmier than the original movie and its series, but I still give the animation a little higher score just for my liking of this movie. As I'd say, the animation's more like Castle in the Sky, despite it's artwork was more of 90s style. And pretty much as dark as the first movie was.
Sound: I was always disappointed with the English Dubbed. And to my disappoint, Kero's voice has changed. Either later in the series, this movie or its original movie. It has changed to sound more like the Japanese Dub (which is cuter). I prefer to watch all Card Captor Sakura movies in Japanese because she sounds more like a little kid in Japanese for her age than in English Dub. And the music was pretty fitting and everything.
Characters: The characters were always a 10/10. Original concept and an imaginative idea of a little kid coming to town and Sakura suddendly falls in love with her. But since the characters have grown up and have entered middle school, they act more differently than in the series or their normal life.
Overall: A very good movie following another movie and focused on a great series. A must-watch and is very watchable.
