Character Analysis
Like Ron, Hermione doesn't get a ton of airtime in this particular film—at least not in terms of character development. She's still brilliant, of course—but we should note that she's also gladly sharing the brainiac spotlight now, when the chance arises.
Just look at how freely she praises Ron for his idea about how to destroy the Horcruxes:
RON: Harry, Hermione and I have been thinking, it doesn't matter if we find a Horcrux.
HARRY: What do you mean?
HERMIONE: Unless we can destroy it.
RON: So, we were thinking—
HERMIONE: Well, Ron was thinking. It was Ron's idea. It's completely brilliant.
Hermione seemed like she had a lot to prove when she first started at Hogwarts, but now that she knows (and knows everyone else knows) that she's the smartest kid around, she seems more comfortable sharing the smarty-pants love.
However, she's still super insightful and clever about things that elude others. Harry says as much when he explains to Ron and Hermione why he's giving himself up to Voldemort in the Forbidden Forest:
HARRY: I'm going there now.
RON: Are you mad? No, you can't give yourself up to him.
HERMIONE: What is it, Harry? What is it you know?
HARRY: There's a reason I can hear them. The Horcruxes. I think I've known for a while. And I think you have, too.
HERMIONE: I'll go with you.
HARRY: No, kill the snake.
In this convo, it looks like Harry realizes that Hermione figured out a while ago that Harry himself is a Horcrux and might have to die. We certainly didn't see that coming, so we're pretty impressed that she would figure that out. (Sure, Harry figured it out, too, but he is a Horcrux, so maybe he had a slight edge in solving that puzzle).
In any case, even though she's been out of the classroom for a whole year, Hermione remains head of the class, for sure.
