I think one of the reasons the Harry Potter Epilogue was so poorly received was because the audience was primarily made up of the Millennial generation.
We’ve walked with Harry, Ron and Hermione, through a world that we thought was great but…
It amazes me how people read things into the epilogue that weren’t actually there. It’s like there’s this desperate effort to find fault with it, because seeing the characters grow up and this one happy moment in their lives is unacceptable. And the criticisms displace it completely from the narrative as a whole and Harry’s journey as a whole.
Harry did end up with what he’d always wanted: a family of his own. And I personally found that beautiful and incredibly satisfying. We know Harry was wealthy; that was established in the first book. But there’s nothing in the epilogue that indicates money was necessary to his or Ron or Hermione’s happiness.
They were sending their children off to school for the first time. That’s a huge moment. The trio had survived the war, due to their own efforts and sacrifices, and raised another generation. Which is beautiful and so hopeful and after everything they went through, everything they lost, I was bloody happy for them.
I don’t see anything that demonstrates “You are exactly like your parents.” Ron’s jibes about Slytherin? Totally in character and he was joking. And Harry’s speech to Albus showed the truth of the matter. (And if you don’t understand why the rivalry between Gryffindors and Slytherins continued and would always continue, then you don’t understand Gryffindor and Slytherin. The Houses’ values are mutually incompatible.)
And naming their children after the dead they’d lost acknowledges the past and the horrors of the war, whilst showing that life goes on despite tragedy. It was a tribute to those they’d lost and, again, beautiful in my opinion.
