Wow... that's about all I can say... This film was definitely different -- different than what I expected, and different from other animated films I've seen. I'm a fan of foreign films, and a fan of animation such as Miyazaki. The animation style in this film was fascinating and compelling; watching this quasi-silent movie for 80 minutes seemed a bit of a stretch. Honestly, this would have been wonderful as a 14-minute short.
While there were some delightful moments and sparks of brilliance, I found the characters overall to be, well, two-dimensional. Mme. Souza and Champion were emotionally opaque, and un-engaging. Perhaps the best character was actually Bruno: capturing the mannerisms of a dog so faithfully.
In summary: interesting, worth a watch, but I definitely wouldn't rent this one again.
