You missed one of the best miniseries, one that still holds up and is emotional to watch, even forty years later, THE DAY AFTER. Watching a bride, on what was supposed to be her wedding week, seeing the devastating effects of nuclear weapons and radiation from them is heartbreaking.

If you cannot remember, Hogwarts has enchantment that prevent Floo Powder travel for security reasons. Plus most modern British homes do not have a flu not to mention a fireplace large enough to stand in.

So the hogwarts express is a plot necessity. You mention the train but overlook a flying car and Thestrals..lol
