Mostly the details of the rarely shown Tropical Land from the TV anime and Manga are well done. Includes resemblance of Tokyo Disneyland and other Japanese theme parks.The story, original in many ways. I like how the whole mystery keeps you guessing till the climax of the movie. As well as some suspenseful and exciting scenes that are memorable.The additional characters unique to the movie are interesting including the suspicious characters on how they interact with the characters we all know.Overrall, it's as good as it gets in my opinion. Those who are into the series will enjoy it including the Ran fans. Only available in Japanese for the time being.
