Can't understand the bad reviews! This series doesn't pretend to provide a deep dive into the superbrands - each episode is only about 45 minutes, for goodness sake! But in that amount of time Helen Skelton manages to squeeze in a bit of the history of the brand, it's popularity, marketing strategy, a brief tour of some of the product production facility (similar to the "How It's Made" series), and also touch on both the environmental impact of the product and the pros and cons of the nutritional value - or not - of the products. That's a lot of stuff to touch on!
She has a breezy presentation style and projects a sense of enthusiasm for the subject, as well as throwing in a touch of humour, and the episodes move at a good pace. All in all, it's a very pleasant way to spend 45 minutes of an evening. And it provides a variety of enough interesting information so that those interested in more in-depth info on some of the topics covered can then Google or otherwise expand their research. Very enjoyable IMHO!
