User Reviews

Completely Engaging! Very creative and entertaining. Similar to Studio Ghibli films, which are fantastic!
19 January 2018 | by rannynmSee all my reviews

The story centers around a girl named Kokone, who I think has narcolepsy. She often dozes off and dreams about a kingdom known as Heartland. Her father is arrested and accused of stealing technology from a famous company and Kokone and her old friend Morio track him down.

I really like the two main characters, Kokone and Morio. I appreciate their dynamic friendship and their personalities. I truly believe they have a bond that can't be broken. Besides these two and Kokone's dad, none of the other characters stand out that much. Of course, I have to talk about the animation. The animation is beautiful. I've always loved Japanese animation and this film is no different. I love the backgrounds of both the real world and Heartland. I love how the characters move. All of it is so appealing. And speaking of visual stuff, the outfits that the characters wear are amazing. If there was an award for best costume design in animation, this film would win it!

The Heartland dream sequences are the best part of the movie. The dreams have their own story, separate to the story taking place in the real world. The dreams are my type of adventure. A kingdom with a combination of sci-fi and fantasy with lots of action? Perfect! It's also really ingenious. Ancien's magic tablet is one of the most original and imaginative inventions I've ever seen in fiction.

I also love the soundtrack. The background music has a pretty orchestral vibe. The music composer is Yoko Shimomura, a famous video game composer known for working on Final Fantasy and Kingdom Hearts. She also composed one of my favorite video game songs, so I got pretty excited finding this out. The one thing that did bother me is that the movie is advertised as a sci-fi / fantasy movie. However, there isn't that much fantasy. The movie has elements of fantasy, such as in the dream sequences, but it doesn't feel as if it is an actual fantasy film. This bothered me just a bit. Also, certain things are left unexplained and that left me confused.

I give this film 4 out of 5 stars and recommend it for ages 12 to 18, due to some mild language.
