Mine's either Whisper of the Heart or Spirited Away.
Whisper of the Heart has my vote, no question. But to be honest, I like them all. Studio Ghibli just doesn't make bad movies.
Porco Rosso for me. But i agree with Glitchipedia, all are good.
Ponyo, Spirited Away, Kiki's Delivery Sservice, Howl's Moving Castle (though I can't remember it very much...) and planning to see From Up on Poppy Hill.
Porco Rosso definetly!
Spirited Away is definitely my favorite Studio Ghibli film.
But all the Studio Ghibli films that I've watched so far are amazing.
My Top 3:
Laputa: Castle in the Sky
Whisper of the Heart
But I love all Studio Ghibli movies. Even the bad ones.
My top 5:
1. Princess Mononoke
3. Kiki's Delivery Service
4. Spirited Away
5. Howl's Moving Castle
Only missing out on fifth - My Neighbour Totoro
out of the TWO i seen i enjoy Ponyo and Kikis delivery service
glitchy you really need to interduce me to more of the films
