I hate to say this because Kaleid for me is at the moment one of my favorite ongoing Type-Moon series, the manga that is, and the arc that the movie adapts is one of my favorite ones , it has so much action, nuance, character development and great visuals there, but the movie lacks almost all of them.
Visually it isn't good, sometimes it looks really good but mostly not, the story and characters are too rushed, and it's sad because Kaleid has solid adaptations overall, they handled Oath Under Snow greatly, mostly because it was an arc with around 10 chapters, this movie adapts an arc of essentially double or triple the size of the last one, and you can really feel that after the first minutes of it.
They did handle the last minutes of the movie much better than the first ones, though again, the manga is the better version by far.
