Giacchino's fine.
Yep. I've liked every score of his I've come across (sometimes considerably more than the film for which it was made).
And I really want him to stay for the next movie (which will probably the last in this series) to make this feel like a trilogy.
The completely different music in TVH (which also was part three of a trilogy) makes it feel like it didn't belong there, and I don't want that to happen to this movie.
