I don't know why people hate it, but I think it's one of the best movies/musical I have ever seen. I was surprised when I learnt that people didn't like it, and I felt so sad. I think it is underrated, and the flaws which haters point out are flaws that any movie would easily have had. The CGI made it better, and the glitches were just little mistakes that should be ignored. It was realistic and cute. I don't know why anyone would hate such a lovely movie. The dancing was graceful, the songs were catchy, the cats were adorable. It's beautiful. I wouldn't mind watching it again.
