I've always had a hard time appreciating poetry. I simply have trouble wrapping my head around it, no matter how I've tried. I just chalk it up to not having the mental temperment for it.
I get where you're coming from, some poetry is pretty demanding, and the on the flip side, there seems to be an incredible amount of crappy poetry out there nowadays (that is also somehow praised). I have a hard time finding stuff that's good, but without being something that interests only academics.
If it tells you anything, though, I managed to enjoy said book even though english isn't my first language nor am I particularly fond of its sonority.
