This is basically an anime series of 22 episodes of 23 minutes turned into a live action movie less than 2 hours, so it feels like lot's of short stories and mysteries compressed which led to omitting the slice of life and the interactions between the main characters. Anyway, for those who have not watched the anime series might be hard to relate to the characters since in this movie we barely get any information about their background but still you are going to enjoy the mystery which upgrades by time passing and make even you thinking about a hypothesis. However for those who have watched the anime series you will find the characters more interesting but less than the anime since there are barely any slice of life, school, comedy scenes which were the missing link in the anime between school genre and mystery in contrast to the movie which feels more mature. All in all it's a good watch worth the 2 hours if you can tolerate the slow pace in the begining but nothing remarkable or unforgetable.
