Warning: I'm bad at answering these types of questions, so I may contradict myself or something. I think first off I like it aesthetically - it's "my kind of thing," (and I feel like I don't have the vocab to describe what my kind of thing is... the dark, the drumming) so I'm sort of sympathetic to it from the outset. I liked the juxtaposition of the film score with the images being shown - or rather, it started to "get to" me emotionally, about halfway through. It made me sad. Not sure if that really gets to why...
