If there is anything that I really dislike in the HP series, it's Albus Severus Potter. What a dreadful name.
Also, I don't like how it seems that nothing has changed, in the sense that the houses are still greatly divided. Harry does tell Albus Severus that Slytherin will have gained a great wizard if he is sorted into Slytherin, but follows it up by telling him that he can choose Gryffindor if he wants it that badly. I always felt that the Slytherin house was wrongly demonized in the books AND the movies, and I thought that after Voldemort died, they would become more united. Even though Draco Malfoy never really wanted to become a Death Eater, he gives his son the awful name of Scorpius or something, which just sounds dark and horrid. I don't know, Rowling could have done so much better with Epilogue, it really is the weakest part of the series.
(Also, I always hoped that Harry would end up teaching Defense Against The Dark Arts at Hogwarts but she made both him and Ron Aurors working for Kingsley Shacklebolt. And then Ginny plays Quidditch for a living. Hermione has the best career, though, working in the Department for the Regulation and Control of Magical Creatures.)
