I dislike most poetry and firmly believe %99.99999999 of all people, including myself, should never attempt it. When I read a bad poem I feel a deep sense of shame and embarrassment for whoever wrote it.
My biggest issue with people who write poems is that way too often they poorly try to use awkward and outdated language so as to imitate past works of great poets. While it's great that people appreciate the past and can read at all, using archaic language doesn't make your poems any better. Trying to sound depressed doesn't do anything for you either. You don't sound deep, you just sound whinny.
My other problem with most people who write poems is that they're just like almost anyone else; they're incapable of thinking up anything worth listening to, much less anything worth reading. I care more about how a poem is presented rather than the actual meaning. I don't expect anyone to come up with something totally new, genuis, and original, and it's nothing to be ashamed of if you can't think of a subject for your poem that's in any way original. People have been writing poems for a long time. Just about everything has already been done a thousand times. At the very least just try to do a good job of writing the ten billionth love poem. All that said, here's my love poem.

La la la la
love your Grandma
Ha ha ha ha

Thanks for your time. I hope you enjoyed that.
