Perhaps because I now sometimes report on them, I'm more acutely aware of school inspections than I ever was before I worked for SurreyLive. Hogwarts wouldn't pass an Ofsted inspection Most importantly in the context of Harry Potter, if the characters are able to travel back in time then why in the blazes didn't someone pop back a few hours on the evening when baby Harry's parents were killed by Voldemort and maybe, you know, suggest they spend the night at a friend's house? 4. Not to get all geeky here, but if you're suddenly going to decide that time travel is possible in your fictional universe then you're opening up a right can of worms. With Harry and Ron she then uses the device to save the day during the final chapters of the story. At the end of the epic third instalment in the series, Harry Potter and the Prisoner of Azkaban, it turns out that Harry's super-intelligent best friend Hermione Granger (played by the brilliant Emma Watson) has been using a 'time-turner' to travel back through time so that she could attend two classes at once because she loves learning so much. So, here's a problem I hadn't really considered first time around. The time turner in Prisoner of Azkaban is problematic After that Sir Michael stepped in and did an admirable job playing the Hogwarts headmaster until the character met his maker four films later at the top of the school's clock tower, which frankly is still too upsetting to talk about. Unfortunately Harris died after he completed filming for Harry Potter and the Chamber of Secrets, which was the second and last of the Potter movies to be made by Home Alone director Chris Columbus. I think the man may have actually been a wizard - he looked and sounded exactly like how I imagine a magic old man in a pointy hat to be. No offence intended to Sir Michael Gambon who is something of a national treasure, but there is something quite wonderful about the performance of the late Richard Harris as Albus Dumbledore in the first two films. The muggle version of Quidditch recently changed its name to quadball (Image: Jack Taylor/Getty Images) 2. All well and good, but what if your team is 160 points or more behind? Why would you want to catch the snitch and condemn your team to defeat by bringing the game to a close while you're still trailing? It's daft, and I am glad to finally get it off my chest. So far so normal (except for the broomsticks) but here's where it gets silly: there is also a "golden snitch" flying around, which is a small ball that scores you 150 points if your team catches it and brings the match to an end. For the uninitiated, the basic rules of Quidditch are these: two teams fly around on broomsticks passing a ball to their teammates and trying to throw it through hoop-shaped goals at the opposition's end of the stadium, with each goal being worth 10 points. I realise this will enrage a lot of people, but I've always thought it was true from the first moment the wizarding community's favourite sport was explained to me. Hopefully you agree with some of them, while I have no doubt that others will spark fierce disagreements. So without further ado, here is my list of six observations from re-watching the Harry Potter films. READ MORE: 'I went to Harry Potter studios 30 minutes from Surrey that families visit from across the world' Sadly I didn't have a spare fortnight to get through all seven books (Order of the Phoenix is so massive that I still use it as a doorstop in my house), but I did find time during a couple of days off to binge the eight movies for probably the first time since the last of them was released a decade ago, and a few things stuck out to me - some that I remember thinking when I was reading and watching the stories the first time around, while others were new. Today's world would have seemed scarcely recognisable in 1997, and I wanted to know whether spending some time hanging out at Hogwarts would still elicit the same emotions as it did when I last entered that universe several years ago. While I don't want to mark the occasion by wading into those arguments, this does seem like a good moment more generally to revisit Hogwarts and see if it hits any differently a quarter of a century after the first book was released. Rowling has been the subject of much discussion thanks to her interventions into the debates around trans rights. Harry Potter turns 42 this weekend according to canon in the wizarding world, and his journey into middle age comes at a time when the legacy of his creator J.K. If you're a true Potterhead then you will know that this Sunday (July 31) is a very important day on the calendar for everyone's favourite boy wizard - although it's a bit of a stretch to call him a boy anymore.
