They switched directors and literally destroyed the "hard" magic rules of the world building. 

Flying death eaters and every duel being the 4th movie's "conjoinning spell" just ruined it for me. Wands became magic guns or lighting  duels.  No depth.


What?... I like to read while I grill...

In all fairness, in the later books, I’m pretty sure they describe advanced wizards being able to cast magic spells without the cantation. So I always assumed they just didn’t have room in the movie to explain how the kids learned to cast spell without saying anything.

Of course, I could be making all that up, it’s been a long time since I read the books.
