Full of interesting ideas and really rather chilling at times, this account of a mental breakdown is fascinating to watch, with Gena Rowlands a glorious choice for the lead. It is in the way that Rowlands is able to carry emotion on her face that makes her performance so stunning, and along with some well used music and effective close-up photography, it is an intriguing piece of cinema, even if awkwardly very melodramatic at times and a tad hard to digest. The on and off-stage action in the protagonist's life is mixed together, and it is sort of muddled in this sense, though perhaps only as muddled as her mind is. The film poses such interesting questions about how much one should or does care, it portrays mental illness, and, it also has some insight into theatre production. It is very good stuff and only really brought down by being fatally overlong, with the content stretched to its limits.
