LOL I know, they do it pretty often! I always catch at least part of it for the previews of the next movie! I have it on right now LOL.
Draco's another good character. I like his vulnerability in the last two books especially. I don't know that I would have wanted him to completely pull a 180 and turn good, but I like how it turned out with the Malfoys, the way that Draco was kind of struggling between the two sides by the end of DH, and how Harry's saving his life essentially served to save his own later, when Narcissa lied and told Voldy he was dead when he really wasn't.
All through DH, you see that - every character Harry has shown kindness or mercy to throughout the series does something to help or even save him in DH. Dobby, Kreacher, Wormtail, Griphook, Malfoy, etc. It's such a powerful message of good karma, what goes around comes around. I also love how each of the Horcruxes was destroyed by someone different - the only one Harry actually got rid of himself was the diary, back in Chamber of Secrets. He may have been The Chosen One, but he would never have survived and conquered Voldemort without the help of his friends.
