Despite the technical limitations of its time,this classic fantasy musical is as magical as ever,but how many modern children get a chance to see it?And why does it still touch an older audience? The story of Dorothy (the incomparable Judy Garland)and her little dog Toto,swept off by a tornado into a world of colour and magic, yet determined to return home,is still compelling,and its direct treatment, terrific performances and imaginative world compare well with formulaic modern fantasy like the Harry Potter films.
