9/10 - Beautiful as its message.
The Borrower Arrietyy/The Secret World of Arrietty doesn't share the beautiful, blossoming and complex character of Howl or the kind of goosebumps ambience Spirited Away would give you. It has its own world. It feels most normal compared to the rest of Studio Ghibli.
What I like in the anime is the romance between the two, Arriety and Shou. Lines like 'Don't be afraid', 'You gave me courage to live', and 'You are beautiful'. I love the metaphor of the two. The film is a huge spark of environmentalism at its finest--'You change things. You destroyed our home' really hit me. The metaphor and symbolisms of these two couldn't be more perfect.
