Spirited Away was creepy but good. I still love My Neighbor Totoro the best as it's a movie with no antagonist, yet it still works perfectly. Still haven't seen all the Ghiblis but have watched many and enjoy all of them on different levels. I think Ponyo was the first and that one is inscrutable when you don't have the mindset of what Ghibli is doing with their stories.
Dramatic recreation of me watching Ponyo the first time:
