I really enjoyed Yeast, and was surprised at how much more emotive the 'unscripted' directorial style is. Although I'm not a cinema student or major buff of any kind really, I found myself fascinated by this more natural way of crafting a film. The characters truly came alive for me, and I found myself feeling real sympathies for them and their frustrations with one another.
The profound constipation of communication was truly palpable at times, and this very fact, kind of eclipsed the need for there to be a more definite tale to tell. For me, the inability of the characters to be wholly at peace with one another, is what this story is all about. As another reviewer explained, this really is a 'universal dilemma,' and a very disturbing and sad one at that.
Mary Bronstein's character Rachel, although depicted as something of an emotional tyrant, evoked feelings of sincere sympathy within me; I'm a guy, but I have often observed similar difficulties in close female friendships. It was very entertaining and involving to watch, and I suspect that this excellent film will leave many viewers with a strange lingering feeling of voyeuristic guilt.
