I'll keep this short -- this movie was a huge let-down. The first quarter/half or so was at least fairly interesting and quickly took a downturn in the second act. If you want, you can stop reading here.
The characters pretty much all sucked, with motivations/thought processes that remained as uncompelling as they were transient -- meaning that not only did they not make sense, but they weren't consistent either.
The only truly interesting character was Krim, a side character who functions only as a punching bag for the story to push it's weird theme. Which is namely that...
The story seems to have no other theme
than shoving in our face that motherhood is next to sainthood and that all we should care about is pumping out children.
The animation was really good, but the story didn't live up to it in the slightest. Characters kind of all sucked or were boring, with the exception of Krim, who was barely shown or explored, and who got screwed anyways. Not only was the theme weird and shoved in our faces, but it wasn't interesting explored in the least, making it not only a weird/bad theme, but a poorly executed one as well.
I can see why people cried during the showings -- probably because they lost two hours of their life to this.
