i liked this film, the message behind it was heartfelt, the animation was fantastic , though slightly disorientating and the historical detail is impressive. the cutaways to frank's imagination are captivating and really symbolic, even just the design of the Nazi's made the film more interesting to watch. character design was also quite good.
however i do have some criticisms. the story at the start of the film is a bit clunky, kitty just kind of randomly wanders around Amsterdam doing stuff like ice skating for no clear reason, though after around half an hour in the story gets better. the animation can be a bit stressful, fluent and interesting yes but it can look weird and unusual at times. i also feel voice acting could have been better but overall it was fine
overall i'd rate this film a solid 7.5/10
