Having read the book, this felt like a toothless adaptation of an ebullient work. It got almost everything right on the outside, but it's just a really a big void. On the other hand, I don't think I would've understand a thing of it and would enjoy it even less hadn't I read the book.
In the microcosm of this film vegetarianism itself is not the focus- it's just that all the characters are fretting over it- it's more about the damage people do to each other and what happens when the effects of dysfunctional relationships surface. This psychology should work, but it lacks something. There was some beautiful imagery nonetheless, so not an entire waste of time.
