I didn't mind any of the pairings or the occupations or the child names in the epilogue. What I minded is that the books seemed to be leading up to a true revolution in the wizarding world with regards to magical creatures and with regards to sorting into Houses at Hogwarts (otherwise, why make us read those interminable songs by the sorting hat OMG), and the epilogue shows none of that. I'd have loved a house elf with a wand in the crowd or a mention that the original house distinctions had been scrapped.

Like the other commenter, I adored Cursed Child from top to bottom.
