"A Woman Under the Influence" is typical of Cassavetes amateurish films with over-the-top performances which indulge improvisation, often to the point of embarrassingly silly moments. Rowlands much lauded performance is quite poor, depicting a nervous condition with all the fervor of a hysterical teenager performing in a high-school play. But I think this is what Cassavetes valued and it's a detriment to his films which often explore interesting issues. "A Woman Under the Influence" isn't a terrible film, but it's certainly not a good one either.
