You might think that an hour-long documentary mainly shot around a slaughter yard and rubbish dump might not make for particularly agreeable television, but trust me, this opener of a three-part series is by turns amusing, life-enhancing and gripping. Producer Will Anderson and director Gavin Searle have done an excellent job of getting under the surface of one of the worlds great megacities. A place that in the space of 50 years has grown from a population of about 300,000 to 16 million today.
