You either love Peter Greenaway's films or hate them. They take much more effort than the usual Hollywood fare, and many folk can't stand films they can't grasp instantly.
Drowning by Numbers is a mixture of metaphor, allegory and narrative shot with immense style in elaborately constructed and richly-coloured sets. The biggest plot thread is the murder of their partners by three generations of women. This isn't crass US TV real-life drama. This is funny, startling and utterly absorbing cinema.
Woven into this is an array of cryptic sub-plots with some unsettling themes and a couple of horrifying denouments.
If you like your plots on a plate, you won't like this film. But if you like to sit back, absorb, and wait for the realisations to come to you slowly (maybe weeks later), this is a very satisfying and absorbing film indeed.
The cinematography, the ambience, the careful pace and direction - not to mention the soundtrack - are really rather extraordinary.
