What makes a bad poem?

 

I think a poem is "bad" when it lacks a discernible point and sounds like prose. People are led to write a poem because they have been strongly moved by some event. They've experienced a strong emotion , received an insight, and wish to capture the experience in words. 

Poetry often makes even poets cringe because everyone has seen and heard bad poetry so often that the form itself becomes taboo, and people are prejudiced against it. What's ultimately makes a poem bad is the failure of the writer to coming that deep and moving experience to his reader that led him write the poem.
