There will be Spoilers in this review.

I'll try to not make this as long as I'd want it to be, but I actually loved this score. Without getting so much into the finer details, I actually felt this music was the most fitting for a Harry Potter film with the exception of the first movie, and perhaps the third. As "Liz" commented in her post, the key thing about this score was that this one reflects the mood of the books and films much more than Williams' or Doyle's did. They are both overall, in my opinion, much too epic. It sometimes sounds more like music for *coughcough* a space opera rather than a series that is much more personal. And here is what attracts me the most about this score: it feels personal.

Look, Hooper's work is in no way as rich as William's or even Doyle's. And I wasn't particularly impressed by his work for the fifth film. But when it comes to complementing what was happening on screen, this score gets a 5 from me. This movie was not about the magic and adventure and discovery of a mysterious hidden world that the first 2 films, and somewhat the third, were about. It's a film that is much less about the wonder of magic, and much more about the personal feelings of romance, heartbreak, internal turmoil and loss. There are basically only 2 parts in the movie I feel were truly "epic" and those parts sounded fittingly so. "Journey to the Cave", around 1:30ish I believe, and Inferi in the Firestorm after 1:10 are the two most epic scenes in the movies, and the music fitted those scenes with subtle perfection. Heck, during that moment in Journey to the Cave, with Dumbledore and Harry in the middle of the stormy waters and the waves splashing by, I actually heard a few people in the theater comment "This music is so epic right now". The same for the scene with dumbledore manipulating fire against the inferi. And the Malfoy's Mission reflects everything going on in the tormented Malfoy's mind and his secret practice perfectly.

A score doesn't have to be more complicated or include more instruments to be more fitting towards the movies. Hooper and Doyle's work is probably better to listen to on its own, but it just doesn't fit the cinematography and emotions on screen as well; there was a marriage of audio and video in this film that was quite impressive. The most personal movie has the most personal music.

I listened back on all 6 soundtracks yesterday, and having watched the 6th movie twice already, my opinion is only more concrete. Maybe I'm a bit biased though, with HP6 being easily my favorite movie thus far and being one of the lucky few who was able to see it in IMAX.
