I've been reading the stories to my 7 year old daughter, and came across this DVD set. I'm afraid I don't share the enthusiasm of the other 5-star reviewers. Firstly, the child actors don't resemble the descriptions in the books. Jack and Lucy-Ann are supposed to be freckled red-heads, but here they have brown and blond hair respectively. Bill is described as middle-aged and balding, whereas in the DVDs, he is young and good-looking, with a full head of hair. Then, the children have clearly-discernable Antipodean accents, which jar with the English setting.
But while the decision to update the series from the forties to the nineties was probably not a bad one (brick-sized mobile phones notwithstanding,) the plots have been altered, sometimes radically, for no obvious reason. The second story in the series, The Castle of Adventure, has become The Wood of Adventure, with a very different storyline, including a rather scary psychopathic character dressed as a monk whom my daughter found quite disturbing. The Mountain of Adventure is relocated from Wales to Bavaria, presumably to exploit the rugged scenery of New Zealand, where it was actually filmed.
The theme music is also rather naff. It is written by Simon May, composer of, among others, the theme to Howard's Way, which it somewhat resembles.
Having said that, my daughter did enjoy watching them, and was less troubled by the accents and the plot changes, hence the 3 stars. They are moderately enjoyable in their own right, but do not expect a faithful rendition of the books, which are among Enid Blyton's best, and maintain a high standard throughout the eight stories.
