It's an interesting topic, and although we're reviving an issue from quite a while back I think it deserves attention and I'd certainly agree with citral. I especially agree with the notion that ideally titles would just be Location - Year. I think it's best to let the viewer come up with their own interpretation. Sometimes (not all the time, and not necessarily in the case of this 'Slender Dreams' shot) I feel that overly descriptive titles are an attempt to rescue an image by drawing the viewer's eye to one particular element or story within the shot. Were the 'Slender Dreams' shot to be, for example 'London, 2015', you would be left with your own story of what's going on in that picture, and should that story fit alongside that implied by 'Slender Dreams' then I believe it would also lead you to question your own perspective on how you view this particular walk of life.
The whole debate brings up an interesting quote in my mind from Larry Fink's book 'On Composition and Improvisation', as recommended to me about a week ago:
'"Don't ever judge that woman, that older woman with the limp or the gait, because you are she. You will be she. You are of her, as she is of you." I still retain that advice today. For me, there is the underlying force of perception and perspective, and certainly, judgment can be a part of that, but it should not be the dominant force.'
I guess at the core of it, we're not necessarily discussing 'judgement' right now, but more the concept of forcing your own interpretation on the viewer. Larry Fink goes on to discuss finding empathy with your subject and finding elements of yourself within the photograph. I feel that perhaps as photographers it's our job to present elements (and undoubtedly a part of that will be influenced by our own thoughts, but arguably that gives the image a personal flair) and let the viewer build up what they think it means from there. Even if you're intentionally hinting at a story in a frame, I think to then state it in the title removes the possibility that someone might see something different.
Ramble over, and hopefully not a complete waste of your time to read this! It's all just one man's opinion, and I guess that's what makes photography an art not a science.
On a side note, if an image has got someone's hackles up then I think it's done well to spark an emotional response, but again, that's just my opinion.
