I don't know . . . I am put off by predictability, and like you said it often seems about "the struggle". It seems less authentic to me because it is like they clothe themselves in "the struggle" in order to make poetry. The struggle, not their own light, makes them sing. But mostly, I think it rubs me the wrong way because I hate direct, obvious emotional appeals to my own emotions, and the aggressiveness of it makes me feel like I am being conned into feeling. I just thought of one guy who was ever so doltishly earnest yet contrived that I wanted to slap him.
Funny, I was not an English major yet love (some) poetry.
Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
I said "I love poetry," but I qualify that by saying that I will, in a totally elitist fashion, discount what I think to be shitty as "not poetry." This includes some poems I've written and probably plenty you all have as well.
