I've looked at the image several times to find interest that would hold me for more than a brief moment to understand the content. I don't think it is there. I didn't develop any intellectual interest in the subject, and it didn't cause me to feel anything noticeable, and visually, it seems flat and mundane. That all sounds worse than it is. There could be something of interest here, and there's no reason why the photographer could not have taken a more interesting photo at that time and place, but the choices made didn't yield a great result. The subject was placed in the middle of the frame in a very static pose. This removes any tension of dynamics from the image. The lighting was blah, and thus no opportunity for developing even the slightest mystery around any of the scene. The direction of the camera to subject is ordinary in the sense of one guy holding a camera shooting at another guy holding a camera. Nothing in the area surrounding the subject is of much interest.
I get that flat-footed feeling. I suspect, if the photographer moved around and looked for more interesting angles, lighting, surroundings, or just better framing, this "event" which was captured could be very interesting. People aren't all that different from one another in everyday circumstances. Meaning, this guy could be interesting just like some guys in more powerful photographs are interesting. It's isn't that he was the wrong guy, it is that he wasn't put in an interesting enough photographic context. Edges of the photograph define what is in and what is NOT in. When you look through the viewfinder, you have to be aware of those edges defining the selected content, not just the main subject in the middle. I don't like to play "what was in the photographer's mind" - but for this example, it is useful to wonder, what about that stuff inside the edges seemed interesting enough to include? (Again, no insult intended. I am just illustrating the point.) I see little of that stuff being useful at all. I think the odd badge on his shirt is probably far more interesting than all that stuff around the edge.
