Castle in the sky, holy shit how have I never seen this, amazing anime for Ghibli
Not really seen any ghilbli films, any order I should watch or avoid?
They range from grounded historical character studies like The Wind Rises or From Up on Poppy Hill, to fantasy coming of age tales like Spirited Away or Kiki's Delivery Service, to man vs nature examinations like Princess Mononoke or Nausicaa. And of course heart crushing works like Grave of the Fireflies.
Personally I don't think you can go wrong with any, but my preference is the following of their more mainstream works as I don't like to recommend the human drama stories until a new viewer has a chance to sample what Ghibli is all about:
1. Spirited Away
2. Princess Mononoke
3. Nausicaa of the Valley of the Wind
4. Howl's Moving Castle
5. Ponyo
6. Kiki's Delivery Service
7. My Neighbor Totoro (this is the most dramatic, reflective of their popular modern fantasy movies)
You're in for a treat. I have almost the entire available bluray collection.
