Although I personally have found Jill Murphy's 1974 The Worst Witch a bit too much like the outline of a novel, with not nearly enough descriptiveness and presented details (as well as an ending that feels rather rushed and even a bit of a deus ex machina that leaves me as an older adult reader a bit annoyed and unsatisfied), I also do in fact and indeed much admire the author for having introduced and having featured as main protagonist Mildred Hubble, a young witch in training at Miss Cackle's Academcy, who is always getting her spells wrong, has trouble staying balanced on her broomstick and faces constant criticism and bullying not only from her fellow witch trainees but often also from some if not many of her teachers (for Mildred Hubble as a literary character in a school-based children's story is seemingly one of the first, one of the earliest instances where a character who is probably afflicted with and by clumsiness producing dyspraxia or non verbal learning disability is portrayed, is actually shown to be the protagonist, the main hero/heroine of a novel, and not just a secondary character looking, peering in on the periphery).
Now in many ways, Murphy's Mildred Hubble really does rather remind me of a female version of J.K. Rowling's Neville Longbottom. However, and this is a heavy duty however, for those of you (thankfully not many, but this has unfortunately happened in a select few online reviews I have read) who seek to claim that Jill Murphy has somehow plagiarised her The Worst Witch series from Rowling's Harry Potter series, well, UNLESS Murphy was able to perform a Hermione Grainger like trick of travelling forward in time, the latter is patently and utterly impossible, seeing that The Worst Witch was published in 1974 and the novels about Harry Potter only started being published in the 1990s. Yes, in many ways, both the format and many of the themes of the two series appear to be linked and a bit similar in scope, but they are still independent entities, independent novels in and of themselves (and of course, while J.K. Rowling might also and indeed have been influenced by Jill Murphy's The Worst Witch and its sequels, and had perhaps and even likely read these books as a child, I also in NO way even remotely consider her Harry Potter series as being too close, too similar to the former, except that both series happen to be modern British school story variants and take place in magic and witchery academies).
Now while I must admit that as an adult reader (and as an older adult reader who has perused much classical literature for both pleasure and academics) Jill Murphy's The Worst Witch has generally and a bit frustratingly felt a bit lacking in details and description, and also often seems narratively and textually choppy and unfinished, I do still very much realise that for reluctant and recently independent younger readers who are not yet quite ready for the more intricately depicted and yes, also considerably darker and ominous worlds of Harry Potter, his friends and enemies, Mildred Hubble, Miss Cackle et al provide a suitable, engagingly entertaining and above all easily read, digested and understood romp and subsequent preparation for more involved and potentially increasingly dystopian fantasy novel models (two and a half stars, rounded up to a solid three stars, as I do enjoy and have appreciated young Mildred Hubble as a literary character, primarily due to the fact that she reminds me so much of myself at her age, and the troubles I experienced at school, not a witch academy of course, but simply Middle School, where being clumsy, being different, putting one's foot into one's mouth, having social connection issues all played a painful and annoyingly important role).
