On a more serious note, while there's nothing wrong with the concept of Hogwarts having various houses centered on different student inclinations, I think that Rowling did a really poor job of integrating that into her worldbuilding. Particularly in the case of Slytherin where there are no good characters (besides Snape I guess, but he's good in spite of being in Slytherin due to his simping for Harry's mother rather than him representing a proper embodiment of his house as portrayed by Rowling) and the main representatives we get are crybaby Malfoy and his dumb & dumber sidekicks who'd sooner fit in Hufflepuff (or perhaps Gryffindor as unvirtuous members given that they're essentially jocks, only that Rowling portrays them as unheroic bullies) rather than Slytherin. And it's also silly in that they're basically a hotbed for the children of those families that were associated with Voldemort in the past (hence acting as an echo chamber for them to reinforce their anti-establishment views), something that the school is supposedly too dumb and/or naive to realize.
And it's also kinda silly with how far the segregation between houses is taken. Ideally I think that Hermione should've been a Ravenclaw (it fits her character after all) and Ron perhaps a Hufflepuff (his family being quite superfluous in a wholesome sort of way, his older brothers being pranksters and so on) as to show how students from these houses intermingle and to avoid portraying Gryffindor as the protagonist house (vs the antagonist house of Slytherin and the sidekick houses of helpful Ravenclaw & comic relief Hufflepuff), perhaps with an added Slytherin character as part of Harry's close entourage.
