Poetry is like visual art or music, sometimes there is nothing to "get". Of course there are ways to approach analytically, but I don't believe that's where the awesomeness can be found.
To me its about connecting to a particular phrase, image, perspective, or description. Once you feel that connection to a certain poem its a lot easier to feel like you understand it.
The poem I always go back to when people say they don't get poetry is:
"
so much depends
upon
a red wheel
barrow
glazed with rain
water
beside the white
chickens.
"
- William Carlos Williams
It's simple and effective. A single image, a specific point in time and place, are being described with only a few lines and yet you can almost reach onto the page and touch it. You can try to see it as an extended metaphor, or take it completely at face value. Either way - it's beautiful.
