1. Mature Progression
This is perhaps my most important argument in my reasoning for a Harry Potter television series. At its core, Harry Potter is a moral story. Yes, the over-arching plot is a young boy destined to kill the most evil wizard of all time, but the seven books are incredibly multi-layered, both as individual stories, and as a collective tale. Note in the later films in the series, the producers have created many cinematic additions which, undoubtedly, have helped reinvigorate the plot and save it from becoming bogged down in a plot which, frankly, is inaccessible to those who have not read the books. Most poignant of these additions were not the epic fight scenes, but rather the small inclusions such as Hermione erasing her parents memories (Harry Potter & The Deathly Hallows, Part 1), which was merely referenced in the book and, also, Harry and Hermiones dance in the tent scene (same movie) which was a tender, friendship moment, help bring the story to life on screen. It is my opinion that Harry Potter is a novel series that depicts the grow of its main characters much more realistically than any of its contemporaries in the 'fantasy' genre, especially one which was initially intended to be for children. Whilst the main trio are undoubtedly children in the first book/film, when the magical bells and whistles are stripped back, and one considers the story carefully, it is essentially a tale of a mentally unstable man who is trying to murder an innocent boy and subjugate a race of people under a strict regime based on the insane principles of 'pure' eugenics. When considered in its rawest form, Harry Potter is not simply a book about wizards, a magic castle or a flying broomstick sport, but rather a dark tale of obsession, sacrifice and love, which could quite easily compete with any current thriller on television. Futhermore, what is so unique about the drama is the pace at which it unfolds, never being too dark or too sickly sweet. Doubtlessly, had it been a television series, it would have progressed in such a way that a series should (but rarely does); more lighthearted initially with increasingly fore-boding, building into periodic, cliff-hanger confrontations and then concluding with the eventual, climatic resolution.
