The first thing that draws attention are the visuals. This is one of the most beautiful anime movies that I've ever seen. The quality of art and animation is absolutely top-notch. It is very bright and colorful, but we're being bombarded with the faerie-like palette with absolute mastery. I would say it is worth watching for the visuals alone. The music and sound production follow in line, complimenting the breathtaking graphics perfectly.
But a beautiful world is definitely not everything this feature has to offer. We are being thrown into a world populated with refreshingly likable characters. In fact, it's almost too easy to sympathize and grow attached to them. It's a rare achievement for a movie set in a school setting - the characters are well written and none of them makes us wish the scene was already over - the plague of irritating cast has been avoided completely.
When it comes to the plot, we spend a good half of the movie wondering what the heck is going on. As it unfolds, it turns out to be a very interesting take on the theme of time travel, and as would be expected from the previous paragraph, it unfolds naturally and is a product of a myriad of choices made by the characters - they behave in a natural and believable way and what we receive is an endearing tale of an idyllic setting disrupted by a mysterious transfer student. Personally, I love this kind of a story - it manages to show how a potentially world-altering event affects characters on a personal level. It certainly doesn't flip everyone's life over, people don't suddenly become detectives and heroes - they are still their old selves, even in a face of overwhelming circumstances.
I can certainly see that this is not a movie that will appeal to everyone, and people looking for action, multiple-layered intrigue and a massive conspiracy would be disappointed. But if you're looking for more of a slice-of-life drama and allow yourself to be enchanted, you won't be disappointed.
In one word - stunning.
