Constant gardener? More like constant boredom... This is a film with a very simple idea behind it: The United Kingdom (and, one supposes, the rest of the West) is using Africa as an unwilling testing ground for drugs. There is the usual collusion between governments, drug companies and other capitalistic baddies, who are willing and able to go to any extremes, including murder, in order to make a buck. Africans are all good (except for those in government, who being part of the establishment, are also baddies) and Westerners are all bad (except for Ralph Fiennes, who seems to have taken a page off Hugh Grant's style book, playing the usual shy, introverted, bumbling but basically charming public school Englishman, and his wife, a fiery activist cum fearless investigator, rather unbearably self-righteous). Africa is nothing but shantytowns and misery. Official London is a nest of vipers. And the movie is, sadly enough, nothing but a collection of one-sided clichés. It is reasonably well shot and made, but it feels like a partisan documentary trying too hard to sell an idea.
I'm not saying that there is no truth in the accusations made in this film, but its obvious, heavy bias detracts from its possible message. No mention of the fact, for example, that African governments have dismissed on occasion the dangerous spread of AIDS as "a foreign invention" and in consequence are far from blameless. It's all black and white, with no shadings.
And leaving aside the message, as entertainment it's also dubious: I've been a John le Carré fan for many years, but when I read this book, I concluded that he had lost the plot. Literally. And the film has not made me change my mind. It's a film that had not made up its mind about whether it wants to be a love story, a description of the dark works of governments and large companies or a socio-political documentary with a large ax to grind. It tries to be all three things and as a result, it's nothing much. Boring.
