The good, the bad, and the question

Good photo
I thought this picture, the first in this "The Big Picture" series titled "African Immigration to Europe," was very well-done. The boldness of the red blanket really makes the subject pop in contrast to the dark browns and blues of the background. It also follows the rule of thirds which I think works well here. And lastly, the expression on this man's face really grabs your attention and captures the essence of the story.

Not-so-good photo
I wasn't crazy about this photo. I liked individual parts of it, like the fallen crane, the anger in the man's face (assuming he's telling the photog to go away ... who knows?). Some parts of it seem out of focus, and it's just busy overall. The guy on the left is distracting, as well as the cut-off guy on the right. I just think the photographer could have achieved a better angle with a little less clutter.

Questionable photo
This Reuters photo was of a serve during a recent tennis match. I think it looks kind of cool in a Magic Eye, playing-around-with-Photoshop kind of way, but I think sports photos look best with the traditional frozen snapshot, with lots of detail, as opposed to the blurriness of this one. My question is when do sports photogs choose to go for a non-traditional shot like this one, and why?
