I was expecting, and probably would have enjoyed, a portrait of a functioning studio with an insight into work practices and the creative process. While there was some of this the focus was more on personal portraits, and isn't pretty! spoilers

• Miyazaki on censorship by nationalist elements and the lack of enjoyment in film making (although I suspect he does protest too much)
• a clearly fractious working relationship between directors Miyazaki and Takahata
• Miyazaki's son Goro is painted an almost tormented soul, airing self doubt about his own abilities infront of producers.
  

This isn't normally my sort of thing but I think someone with only a passing interest in Ghibli would find this worthwhile.
