I watch a fairly high amount of movies. I enjoy most of them, at least somewhat, but the studio from which I have the highest concentration of enjoyment-per-movie is definitely Studio Ghibli. Studio Ghibli is an anime studio from Japan. The art in their movies is breath-taking, the storylines, while not always their own, are incredible.
One of their movies, Spirited Away, won Best Animated Feature at the 2002 Academy Awards. It out-grossed Titanic in Japan. My favorites of theirs (also my favorite movies overall) are Whisper of the Heart (which is probably my new #1) and Kiki's Delivery Service.
