I ship Harry/Luna in the films. I could probably ship them in the books, too, except for where my unexplainable urge to conform to canon comes into play. I used to ship Neville/Ginny and Harry/Luna, though.

I HATE Ginny in the films; she's so boring and basically feels like a piece of talking cardboard. No offense to Bonnie Wright, but she's a terrible actress.

I love Draco and Blaise (especially Blaise) in HBP. I don't remember the creepy Slytherin girls, but it's been a few years since I've watched it.
