Always.
This is perfectly timed, because the Syfy channel JUST finished a 3 day marathon of all the Harry Potter movies. So while my favorite story is Chamber of Secrets (I'm obsessed with the basilisk and just the lore of the chamber itself), my favorite Harry Potter moment is after Voldemort thinks he's killed Harry in the Forbidden Forest and carries him up to Hogwarts. Voldemort is celebrating and talking smack to everyone and then Harry just rolls out of Hagrid's arms to reveal his fake-out. It cracks me up.
The looks on Voldemort & the Death Eaters' faces of "Oh, this did not go according to plan" combined with Harry's smug look of triumph really does it for me.
And a big shout to Narcissa for not selling Harry out. As Lily, Molly, and Narcissa all demonstrate, motherly love knows no bounds. Given JK Rowling was a nearly homeless single mom at the time she began the stories, that doesn't surprise me one bit.
