I just got done watching Cardcaptor Sakura - The Movie and I enjoyed it quite a bit. As far as anime movies go this is one of the better ones I've seen. The story has to do with Sakura winning a trip to Hong Kong. Of course, once she gets there some strange things start happening around her. This movie was really enjoyable. With the full cast of characters making appearances. We also get to meet a bit more of Li's family, including his mother and his sisters (who are hysterical).
An amazing job was done with this DVD. The video quality is amazing and the sound was kickass. If you have a system with 5.1 sound it really makes a difference. This one has 5.1 available for both the japanese and english versions. I haven't had a chance to check out the dub of this, and I probably won't do more then a sampling of it. The dub is done for the US version, Cardcaptors, so supposedly has all the name changes.
If you are a fan of CCS I highly recommend it.
