Let's say you are Kay Nesbitt. Would you fall in love with a person like Harry Allen? Let's say you are Harry Allen. Would you regard your 'best friend', Richard Langley, still as your best friend after he has stolen your girl; instead of kicking his ass? Let's say you are Pat Allen. Would you stick to a dead marriage, although you are in love? Not likely. Implausible & unconvincing; no suspense & no thrill.
One of those films I never heard about until I found the DVD laying around in my mother's collection. It suffers from tonal shifts and uneven pace but it was extremely pleasant to discover this offbeat, witty and surprisingly dark little film. Plus, the performances are pretty incredible.
