Production Design
Straightforward, But Action Packed
We're dealing with pretty straightforward action adventure fare, with one major storyline that follows the template we've seen in the first three films: Harry Potter balances normal teen stuff (dating! dances!) while confronting strange and sometimes dangerous wizard stuff (evil Dark Lords! Death Eaters!).
This time, of course, there's a notable romance plot as an undercurrent/distraction from all the dangerous stuff, but the action/danger elements are much more front-and-center. So, we'd say the movie is pretty uncomplicated—and we mean that in a good way, of course.
