Certainly an improvement over the confused Nausicaa and the vapid Ponyo, both of which it's hard to imagine anyone over the age of 5 enjoying. The animation in Porco Rosso is of a wonderfully high standard, consistently wowing you with its incredible attention to detail and the way the screen is always teeming with life and movement - making a lot of anime look static by comparison.
This makes it worth the price of admission alone. But add to that a perfectly coherent (if rather simplistic) story and you have an enjoyable anime. My problem with Ghibli remains that a lot of their films are just so damn childish. I know that's the point - I know that Miyazaki, by and large, makes anime for children, but I can only dream of what he could achieve with such a talented animation team if he made a film purely for adults.
