I'd give it 10 stars if it was making sense. Or to put it simply, think it out carefully and you'll realize - it couldn't happen the way the movie explains it. Only problem is - most of the climax of the movie doesn't really make sense. Once we got to know and like these lovely characters we just want to see the story through and know how it all ended for them. Some of the plot twists can be spotted miles ahead - it doesn't matter.
So despite obvious similarities with Zootopia I still enjoyed it wholeheartedly. It's not original - I couldn't care less - once again: originality as is, is overrated in my personal book. This one, as another reviewer has already said, has wonderfully written characters (obviously - written and performed).
