To add to Clare's comments, these days, there are a million ways to muck up a photo by pressing a button or two in Instagram or some other "effects" program. BFD. So what. The novelty appeal of such "looks" will fade with time in most cases.
In contrast, there are many, many fewer ways to take a good photo and have it get all the way to the viewer in that condition.

PS - Note, among the users of such efx, there will be artists who consistently use a particular look to make a political, environmental, etc. statement in a visual way. For example, if this was one image in a series of 10 other guys like this, all taken in dingy surroundings and all mucked up in the same way, I would have a good sense that the artist wasn't just taken by the novelty factor. I would start to wonder if perhaps the artist was trying to enhance the dingy, self-absorbed look or perhaps some other look.
PPS - Just for yucks, here is an image that you, the OP, have never seen before, have no connection with, and couldn't have ever previously seen exact look . This image started life as an ordinary baby shot -- nice, well lit, superbly well color corrected, etc. Then, for this thread, I had my way with it.
Do the efx I applied mean anything to you emotionally, or are they just a wowie-zowie novelty? How do you think the grandparents would react to the efx? What about if you showed it to 10 random people on the street. Think about this. BTW, it took me less than a minute or two to radically transform the starting image into what you see - just button presses, hardly any thought was required.
