How to nearly ruin a movie with awful music: Exhibit A
This soundtrack nearly took me out of the film. It was so out of sync with the tone and pacing. I can't help but think Manhunter might've aged better with a different audio direction and didn't lean so heavily on such generation-specific music (not including Iron Butterfly at the end).
For instance, think about how silly Star Wars would seem now if it was packed full of disco music.
Whether you agree or disagree, can you think of any other movies you liked whose soundtrack you couldn't stand?
