I enjoyed it. Reminded me of Classic slapstick comedy but modernised and .. I would like to say targeted for children but it's not really a children's film. The preview did make the animation dull looking but it looked fine during the film. I laughed throughout the entire film; it has stupid antics, funny action scenes and I really enjoyed it. I really don't get the low rating.
I guess it's just a taste thing. If you like slapstick comedy, I think one would enjoy this; nothing has to be perfectly made, just has to be enjoyable and I enjoyed it.
The story is about two things: first a robbery of a ruby, which a dog accidentally swallows; and a cat, who is named 'Diva', and does in fact live up to her name. Sort of like 'Homeward Bound' but not really, just a cat and a dog on a journey to find their owners who are looking for them and they keep getting further and further away from them. Also has a sense of bonding with the two 'owners' looking for them and the relationship of the dog and cat. The dog's name is profane; I'll refrain from saying it here but I, again, quite enjoyed the film. Something to watch when you're tired of all the seriousness of the world itself.
