In an interesting interview with SciFiWire, HBP director David Yates says that sure, there’s going to be a lot of darkness in Harry Potter and the Half-Blood Prince, but a lot of lightness as well. Here’s what he had to say:
This film is a bit more sexualized than that. You know, in a way. We don’t see sex, but it’s kind of in there. And the relationships are a bit more complicated and romantic and convoluted. So we’re pushing into new emotional and kind of physical territory for Harry Potter.
Yep, I’m going to have to agree with this one. We see Harry and Ginny together, Ron and Hermione finally admitting they might have feelings for each other (kind of), and of course Ron and Lavendar, which is going to be quite embarrassing to watch, frankly.
