Though most say it was a, and I quote, "A Cat-astrophe", I purrsonally loved the film. It was very awkward the first few minutes, but as you continue to watch, you become entranced by this movies emotional and physical movement.
Most people though were freaked out by seeing the stars' faces on the cat bodies, but remember that the actors, even in the Broadway hit, don't look like purrfect cats either. You can still see their human features even in the play, and unless others wanted them to look like actual cats acting in the movie instead of humans playing cats, I don't see a problem with it.
Overall, a very good and enjoyable movie!
