Now Go is basically an essay about Studio Ghibli's portrayal of grief and what that means to the author. It isn't really just about grief in Studio Ghibli movies, and sometimes the link feels a bit tenuous. I can understand feeling a very strong personal connection to movies, and seeing things in them which reflect on one's own grief and loss, but it ends up not being an inquiry into grief in Studio Ghibli, but very much the author's grief and Studio Ghibli. The actual analysis of the movies as texts is fairly surface-level.

I also wasn't super convinced that the author understood that, for example, Howl's Moving Castle is based on a book by Diana Wynne Jones, and not something that Miyazaki came up with in his own head alone. He didn't engage at all with the anti-war themes of this adaptation of Howl's Moving Castle, which are very much Miyazaki's thing, developed out of very small elements of the plot of the novel. It would have fit nicely with his themes, but... nope.
