J.K. Rowling admitted once that Hermione and Ron's relationship in Harry Potter shouldn't have happened, and that Ron could never make Hermione happy.
It's seventeen years after the Battle of Hogwarts, and Harry Potter's son, Albus, is nervous that he might end up in Slytherin. Harry, however, sees no shame in being in Slythering, but, he says, if you really don't want to be in Slytherin, the house will listen to your suggestions. After all, he was nearly put in Slytherin himself - or was he?

There are a lot of people who accuse Rick Riordan of ripping Harry Potter in his series Percy Jackson and the Olympians. After all, the two stories have a lot of similarities. But they also have some interesting differences.

You know what's annoying in a main character? It's when the movie/series/books display him/her as this socially awkward person in the beginning of the movie, but by the end of the movie the character is perfectly "normal". Or when they weren't even that "not normal" to begin with.
