The Cat Returns is the latest movie from Studio Ghibli. A light-hearted movie, it expands upon the characters of Muta and the Baron, last seen in the Studio Ghibli movie "Whisper of the Heart". The movie is similar in "Spirited Away" in that it starts in modern-day Japan, and then shifts to a parallel world.
"The Cat Returns" is about a girl named Haru who saves a cat, and finds herself whisked away to the Cat Kingdom to be rewarded, however, none of the gifts are really suitable for a human being. It borders on comedy and fantasy, and is probably closer to the feel of "Kiki's Delivery Service" or "My Neighbor Totoro" than "Spirited Away" or "Princess Mononoke".
I found myself enjoying the movie quite a bit.
See? I told you The Cat Returns is a good movie and that the Infernal Affairs movies aren't that great overall. >=)!
