What's with all the internal dialogue?
During this, every scene is opened by some observation by Whitacre, often some fact which has no relevance whatsoever to the plot of the movie, or what was happening at the time.
If he was internalising what he was going through at the time, it could have worked. But the irrelevant observations, while interesting initially, started to annoy me halfway through the film when it was done over and over.
Those little tidbits took me out of the film, and might have worked better in another film altogether.
