If you didn't like those two you probably will not like this one.
I saw Spirited Away less than a week ago for the first time, and although I didn't love every scene or every character - which for me is quite often the case with animated movies - I think it is better than Kiki because it is more unique. Its dreamlike atmosphere is mesmerizing. I have to admit though that whilst watching it, at some parts I had mixed feelings about the movie. But it's one of those movies you appreciate more after you have seen it. And who knows, probably I'll love it after another viewing.
But I hope My Neighbor Totoro will be better than both, and hopefully I'll include it in my 'great movies' category, that is 9/10 or higher.
