An achingly sad vision of Harry's postwar life, and much more realistic than JKR's dissapointing epilogue. Life is not a happily ever after; the interaction between the characters was very much in character, no matter if they were polyjuiced or not.
But my favorite scene was Harry channeling his Aunt Petunia, waging war on his bathroom grout with a toothbrush and bleach, all the while wearing a pink apron.
