I loved loved loved the Epilogue. I thought it was done amazingly and it really hit me hard when I saw all 3 of them grown up with their families and sending their children off to Hogwarts.
The music was just...*speechless*.
They couldn't have chosen a better music piece to play for the final scene. I thought Dan, Emma, and Rupert played their part brilliantly

I am soo glad they didn't cast 'strangers' to close the series, it had to be them.
If anything, I wish they had made it a bit longer and maybe chosen a better angle for the very last shot of when they zoomed in on the trio because they sort of cut Ron off.
Anyway, the Epilogue is one of my favourite scenes in the movie
